Did you delete all files before reinstalling?
If not try to delete (move if you want to be save) the files in the cache and unpack folders
One of those 2 should be the solution to your problem IIRC.
If that doesn't work do a
/who gm
in game - you will get a list of online csr in your sys info and can ask them for help ;-)
I deleted the whole directory after uninstalling and didn't find anything elsewhere (the game doesn't seem to put anything in "My Games" or the like?) to make sure all settings and such are reset.
I guess I'll give /who gm a try.
