Bitpim

Help I put some skins on my phone and they bricked it. I was able to delete all the contents of the skin file in p2k commander though but once i dd, the file dissappeared. I tried using Bitpim to delete the empty files but I get to the filesystem but when i click on 'mobile' it reads ubsy then nothing happens. I cant acees the files. I did a seem edit to unloock qpst file acess and it still wont work. Can anyone help me! Thanx.
