Hi there!
While we can't send files, we can help with the problem. Could you post the error report back here please? It's telling us what's wrong, and then we can tell you how to fix it.

i dont know what that one is ... but it was in the crash reports

1st one, it has problems ticking a screen. Don't really know how to fix. 2nd one was from extreme lag or something, like for example, if you blow up a whole bunch of TNT and it crashes, it'll give you that error. I don't believe the 2nd one is part of the problem, just something that happened, but the 1st one is a separate problem for servers. Don't know how to fix, but it's a problem with ticking GUIs, this could be a hint for anyone who wants to help, I guess. :unsure:
