SoulSeekQK crashes when setting shared folder

When I try to share one of my removable drives SoulseekQT build 11/16/2012 locks up, becomes "not responding" and windows Vista closes it. worked just fine in previous build and before windows reassigned the drive a new drive letter... I've tried to get windows to reassign the drive to the previous letter but no luck. any way to get SoulseekQT to purge it's memory of the drive letter?
thanks, -M-13...

In extreme cases like this, you can search your computer for the SoulseekQt configuration file, soulseek-client.dat and move it or remove to start configuring your SoulseekQt client from scratch. If you can't seem to find it try installing Search Everything on your computer and using that to search.
