Joining Server

[Short7]

Hey guys I can usually figure this stuff out on my own but last night I was having problems joining because of maps which I can usually delete, but I made the mistake of deleting a lot of shit from other servers that I haven't played in forever, and then deleted one of the RotU packs thinking maybe I could just re download it.  Now I cant access the server because of some kind of weapons pack.  Any quick or simple solutions to this? Possibly just deleting all of my files and re downloading UO?
