i cant use admin_gui plus and all my add-ons wont work
Look for syntax errors in your 'ADD_ON_LIST.cs' file. Start up the BL server and look at the remote console output. It will print a syntax error if there is one. Remember, if a modder names their add-on incorrectly, it is their fault for being an idiot; it's not a problem with HammerHost
and my music has .oggogoogogogoog at the end of them now
This was an old bug 1 week ago which only existed for a few hours. Delete your .ogg files and re-upload them (with FTP).
