Pastebin the whole log. How much memory does your PC have total?

Update your forge to the latest available for the version of MC you are using. Are you building a custom pack?

Could you see if this issue applies to you?

could you re-upload your most current version to dropbox?

I don't know of any pack that already includes those mods. You could use Tekkit Legends or most any 1.7.10 modpack, and add: https://minecraft.curseforge.com/projects/archimedes-ships/files/2207285 and https://minecraft.curseforge.com/projects/worldedit/files/2309699 to your mods folder I highly recommend you read https://minecraft.curseforge.com/projects/worldedit if you plan on making much use of it. There are other things you can download to make it more useful.

pastebin a log

attachments do not work, use pastebin

you just want that one file he mentioned. And it goes in mods.

Nah, I did a lot of Tekkit before branching out to custom 1.7.10 packs.

Tekkit is a 1.6.4 modpack, so whatever mods you want to add must be that for that version of MC. There is an old Alpha build of Worldedit for Forge modpacks https://minecraft.curseforge.com/projects/worldedit/files?filter-game-version=2020709689%3A326 You can read about it there and download it to test. I have not tried that version. I don't think there is an Archimedes ship mod for 1.6.4. Perhaps there is another mod that adds airships for 1.6.4.

See if this recent Nvidia update issue applies to you

You have the Nvidia issue, rollback.

This does take time.If the free assistance you are getting here is not quick enough, seek help elsewhere or fix yourself. I've did find a fix for that, and found many more issues. Adding Smart Rendering fixed that https://minecraft.curseforge.com/projects/smart-render/files Applied Energistics complained, so I updated you from RV3 beta 1 to beta 6 https://minecraft.curseforge.com/projects/applied-energistics-2/files/2296430/download I then grabbed a version of AE2Stuff that works with Rv3, https://minecraft.curseforge.com/projects/ae2-stuff/files/2270295/download and remove the other one You had the wrong version of ActuallyAdditions, use this https://minecraft.curseforge.com/projects/actually-additions/files/2274681 and remove the 1.11 version You had the wrong thaumicenergistics, use https://minecraft.curseforge.com/projects/thaumic-energistics/files/2295264 remove the other version. Fixing all this reveals more Biome ID conflicts.

attachments do not work here. There was a recent Nvidia update that breaks Java, rollback if you updated and have Nvidia otherwise, pastebin your full log.

Could you upload to dropbox again, with all your changes?

There was a recent Nvidia update that breaks Java. See if this applies to you.

Perhaps your Nvidia drivers auto-updated to the broken version again.

Have a look at the 1.7.10 pack, http://www.technicpack.net/modpack/the-1710-pack.453902 It is a large 1.7.10 kitchen-sink pack.

remove the AntiID mod, it's not working for this pack. Your problem is going to be Biome ID conflicts for awhile, you have a LOT of mods, and many conflict with BoP's Biomes. It's going to be a pain, but the crashlog will tell you what is conflicting.

Learning is fun. If this is your first modpack, starting with a 300+ mod monster is not a good way to go.

https://www.dropbox.com/s/b23ohf5m2kxw4ml/modpack.zip?dl=0 You still had a ton of Flans stuff in \mods instead of in \Flan Launches to where it complains of Biome ID conflicts, you will have to find a bunch of free Biome ID's for the Erebus to use, or remove the Erebus. That antiIDconflict mod I referred you to earlier did not work out, so I'm afraid you will need to figure this out on your own.

Does your newest dropbox link have all your changes in it? I'd like to download and see.

Backup whatever single player worlds are important to you, and try deleting C:\Users\neftali\AppData\Roaming\.technic and try re-installing the launcher and try again.
