I cant seem to get AMP to run the server
Crash Report: https://paste.ee/p/eCUrZ
Your arguments are invalid. There's a value missing after MaxPermSize.
Then you need to check the startup script for any custom arguments that are needed and copy them into AMP.
Also make sure you're not running as the Administrator user.
its not just this pack its any pack I have tried other packs such as Homestead, but to no avail, no packs will run with AMP.
SevtechAges will run through Cmd just fine, I copied the mods directly form the server files from Sevtech to AMP, then mached the java version, but still they will not work. If I dont use AMP the Pack will run, So this is a problem on AMP's Side
This looks like a bug in the server, you should give that crash report to the mod developers.
