File won't check in..

Hi,

I'm having trouble checking in a file in Souregear Vault which I have
already checked in and out several times in the past without a problem.
I get this error message:

[8-1-2004 16:22:52] Server unavailable for transaction end
[8-1-2004 16:22:52] Transaction failed
[8-1-2004 16:22:52] Item $/src/Xyanide/build/Player.cpp caused the
transaction to fail: Could not apply the delta.
[8-1-2004 16:22:52] Transaction failed

I've already tried to undo the check out, the check out the file again
and re-try to check it in, but I still get the same error. Quite
annoying... :(
Other files still work fine, it's just this one.

Regards,
Jeroen Schmitz
