Restore My Docs local after tweakui move

Hello! I just installed new 60 gig hard drive in win98se system. I moved the location of My documents to the new hard drive (E:) using tweakui. I cannot install any programs because they all state that there is an invalid character in the path to My Documents. I have tried to reset the location back to the c drive but My Documents is not listed in the lookup list for changing location. I have also tried right-click and properties on the My Documents shortcut on the desktop and reset back to the c drive but it does not reset the location. Nor can I install any software until I get the location fixed. All assistance is greatly appreciated.
