Then it could be a server issue with the map itself.
I would notify a Staff member via PM of your issue - or leave this thread open for them to read and inform eachother of, which will then lead to the Server Host, Razmirz, to fix the issue.
If you'd like to play on a character you've gotten stuck in the Valley because of this server problem, try the 'Go Home' option in the User Panel and then try logging in.
