"java.lang.OutOfMemoryError" That means you have to allocate more RAM. Launcher Options > Java Settings. And please don't say you got 32-bit java.

Then you do not have 64-bit java installed. You can easily check by opening BLA and typing "java -version". The returned message will contain 64-bit if you have 64-bit installed. Otherwise, you have 32-bit installed. In that case, go to java.com and select the offline 64-bit java. Do not choose the online java download, as that will *always* download 32-bit.

...The day people stop uploading .rar files when its obvious they need .zip files.

Use Java8u51 instead. http://javadl.sun.com/webapps/download/AutoDL?BundleId=98428

Protip: Do not use java 32 bit.

Which has zero to do with technic? You should be having that conversation with Mojang.

Change keybinds for the Galaxy Map in Controls to some other key.

Make your own post, include your own logs.

Like, maybe its important that we know what the modpack is, or what the download link for the modpack is.

Like, you know what you changed. Change those IDs again, but use the "suggested ranges" instead of just causing more ID conflicts by choosing IDs that are already in use.

So. Who are you on technicpack? Anyways, just report yourself and include the new username you want. That's the fastest.

You missed the one where the launcher only takes .zip files, not .rar files.

No, I mean don't use sites like 9minecraft for your mods. because that's EXACTLY how you get these issues.

I'm going to spell it out for you. D O N O T U S E 9 M I N E C R A F T F O R Y O U R M O D S F F S. And check your dependencies.

Remove Gregtech and Numina/Powersuits for a bit, fix all your outdated mods and missing dependencies, then add gregtech and numina/powersuits again.

...10/77. That's all the mods that *might* be from a legit source like Curseforge. Everything else, rubbish sites like 9minecraft. Like, don't do that. Only use Curseforge. I have no idea where to even start with this mess, other than changing all mods to mods from Curseforge.

Change the download link to ?dl=1 instead of ?dl=0. Also, what is modpack.exe? That's never going to work. Follow the guide: https://technicpack.zendesk.com/hc/en-us/articles/204199345-How-to-make-a-Minecraft-modpack

Canned response from one of our bots: Please download this file, then RightClick->Run as Administrator. This should clear Java Settings that are being stored in your OS, which interfere with Technic.

What's that modpack even?

Then you do not have the same issue. Make your own thread. Include your own logs.

Are you playing a 1.6.4 modpack?

Why do you have preferIPv4Stack=false?

Check if java is still installed correctly. You can do that by opening the cmd exe on windows 10, and typing java -version in the screen that opens. Tell what you see.

Not. Too much has changed. You could potentially use a 1.5.2 world on a 1.14.4 server, but not the other way around. There's no backwards compatibility for older versions of minecraft.

So... You tried using a 1.14.4 world on a 1.5.2 server... Ya, that's not going to work. Small miracle you were able to join that server at all.
