Infinity Elvoled Modpack crashes?

Hello me and a couple of friends have a Minecraft server with the Modpack Infinity Elvoled but my Mincraft always crashes as soon as I start it my system is sufficient locka I also gave Mincraft enough ram. I tried a lot, e.g. Because I got an error that said that my 1.7.10.jar file was corrupt, it was replaced by a friend and the error message was no longer there. But it crashed again with the error code 1 tried to fix it as it was described by googel but it didn't work

Reinstall it. Maybe then.

Are you using the normal Minecraft launcher or another one for the modpack?

FTB we also added a few mods

I do not know him. Otherwise just reinstall everything (Den Launcher and / or the Modpack)

The launcher is called FeatTheBeast by Twich and I've already tried it, I think my problem is a little deeper

Well then I can't help you at first.

Thanks anyway

No problem.
