Palm Treo 700P and Documents To Go

I installed my Palm software and had it working no problem. I made the
mistake of installing the Documents To Go software b4 I checked
comptability. After locking up the computer on hot sync, I uninstalled it.
but now when ever I reboot I get this error:
The Notifier file 'C:\Program Files\Documents To Go\SyncDlgN20.dll' Was
not found. Notifiers are used by hotsync manager to inform other
applications about syncronizations sessions Please check your configuration
to correct this problem.
Hotsync manager will skip this file.

I found a refrence in the registry for this file.
HKEY_USERS\S-1-5-21-667740120-947673207-539467700-1000\Software\U.S.
Robotics\Pilot Desktop\HotSync Manager

How can I stop this error? I did reinstall the program and the error
stopped, however, I cant sync with it installed so I uninstalled it again
and the error came back. Can I delete the reg entry? it is listed as
Notifier0 and there is a Notifier1 through 6 after it.
