Changing Source Directory After Install (8.0)

Hello All : Thanks to everyone who helped me with my installation. I finally got it to work! I decided to (perhaps foolishly) delete the source directory on my Windows partition. I later wanted to update my installed system, but YaST2 will not change the source (it says it can't mount the source). This would not be that hard to figure out, except that I'm trying to have it change to a FTP server that has the entire suse directory. Any help on how I can get this done? I want YaST to install from FTP. Thanks a lot, Burhan
