There's another way to fix the startup issue, if that's what it is.
Open Regedit and drill down to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run

If you see BearShare in there, delete it.

Once that's out of the way hit control-alt-delete, go to the Processes tab,
right-click BearShare and select "End Process". BearStart should be able to
start it now, unless someone has set a policy blocking you from the date and
time entirely.

To remove that policy it's a lot easier if you are using XP Pro.
You didn't mention which version of XP you have there.

I highly recommend a freeware program called TweakAll. Among other handy features, it allows the user to view and modify (change/remove/add) the startup files. This is much easier than manually editing the registry.

Aaron, I tried both of those processes, and I didn't see anything even resembling BearShare in either spot. Would that be a bad thing or a good thing?

Rowsdower, I am going to try your program next. Thank you both for all of your help!

P.S. Are you an MST3K fan?...

Yes, I sure am! To enhance the reference, I just added Rowsdower's handsome face as my avatar.
