wont let new members join

hey ive been checking my forum to see if it functions the same since the last incidentnon the servers and now its been a wreck. ive changed the default language back to english and when i install a portal it returns back to arabic launguage even when english is the feault launguage. when i try to register all i do is click "i agree with the terms and conditions" and it says "username is already taken" and all i do is click "i agree to the terms and conditions" i dont even fill out the blank fields yet. i dunno if its just my computer or if its with eeryone but can someone please look at the forum and see if its working right? i checked the admin panel it doesnt say anything about forum vaation or holiday and im sure ive made it so it auto activates. whats going on?
