I was in the middle of upgrading my forum to the new 2.3.3 version when the browser crashed and now I can't do anything. Can't login, can't register, see users, run /upgrade script or /install scripts. The forum's there, I just can't do anything. I uploaded all of the files and changed CHMODs. Don't know what else to do. Any help would be greatly appreciated.

Here's the forum: http://example.com/51c707/
