Error creating a server of "Extended DireWolf20"

[denny994]

Hi to everybody,

I recently download the server for "Extended DireWolf20" but when I try to Start it the server stop working and appears this at the end of the log:

[19:23:52] [Server thread/WARN] [FML]: Can't revert to frozen GameData state without freezing first.
[19:23:52] [Server thread/INFO] [FML]: Applying holder lookups

[19:23:53] [Server thread/INFO] [FML]: The state engine was in incorrect state ERRORED and forced into state AVAILABLE. Errors may have been discarded

 

If this part of the log is not important i can post all of it.

Please help cause i'm not able to find a solution by myself
