[Help, please] My custom modpack doesn't launch, nor does it give error messages.

[Virdex_]

Here it is: https://www.technicpack.net/modpack/ad-maiora.1153396

I have no idea why it doesn't start, since I followed this guide: https://www.technicpack.net/article/building-your-own-modpack.7

Please, I need support. This kind of things is frustrating...

[Melfice]

I downloaded your pack, and had a poke-around. I can't figure out what's wrong with it.

However, the guide you linked to may be outdated. Try this one instead.

Hope that helps!

I will try and let you know if the situation changes, thank you!

Oh, well. My bad, there was an error with ItemPhysics so I just removed it. It was not even that hard to find.

I guess this topic can be closed?  Edit: doesn't work. Again.

So, what was wrong then? Wrong mod version? Incompatible with another mod? Forgot a dependency?

I'm curious, since I couldn't find it easily. (Not that I have much expertise, mind...)

I don't know, it just said something about the creative mode inventory.

By the way, the pack doesn't work anymore. Wtf?? I think I'm giving up, because there's apparently no reason. I removed all the mods, and it still didn't start...

[Melfice]

Right, so I've got the game going, and it's complaining about these being for the wrong version of Minecraft.
That seems like a big issue. Removing them brings me back to the launcher, however, with a crashlog complaining about DaVinci's Vessels.

EDIT:
Replace the mods mentioned in the screenshot with the right version, or remove them. Then, go into the "Main" config of "Moving World" and change "B:"Allow other mods to add to the whitelist/blacklist? NOTE: Turn off if you want to remove the default blacklist/whitelist"=true" to "false".
That allows me to start the game to the main menu.

EDIT 2: Electric Boogaloo:
Huh. Stuck on loading the world. Interesting. It's not crashing, but it appears to just... not want to load.

EDIT 3: Edit Hard With A Vengeance:
Removing the LiteLoader jar from the installation fixed the loading issue. I can't predict what kind of issues this might give, but I'm in a world right now, and it's playable.

Oh. I found the mysterious reason: I changed the java version to 9.0.1 (64bit), because I had to give technic more RAM. However, changing it to that version of java doesn't let me start any modpack.

But, why ç_ç

If I select the 32bit version I can't give more than 1GB, which makes the game crash in the loading screen...

because neither Forge or Minecraft are compatible with java 9.

Get java 8 instead

Oh. Thank you!

In fact, thanks to the both of you for your time. 

Edit: Still doesn't work with java 1.8.0-151 or 1.8.0-152

Edit 2: Works! Yay! Well...  Let's just hope everything is ok by now so I won't have to add an Edit 3 where I announce my death.
