Not exactly an expert at setting up servers, but every time I try to set it up, it gives an error after confirming EULA. Any help would be appreciated. (Sorry in advance if this is the wrong place to ask)

Which version of the pack, and it seems like you edited/corrupted config for serverstarter.

1.1.4. Haven't edited anything.
