Messing around with that rather outdated version is pointless honestly. Call your hoster to install the latest version for you. This isnt about to not-help-you, but think about security. What use has a newly themed blog with all your work in it, if it could get exploited/hacked by some idiot cause its an old version? I think you should update first and then look for cool new themes. and solving one problem fixes the other. just write them a mail. theyve been so kind in the first place.. why not ask for a upgrade.

edit: n dont forget to backup your database ?? better save then sorry. who knows what those guys will do for that upgrade. if they do a fresh install everything is gone. just a hint. doh!
