Cannot view toolbox and errors using Help

[Christine]

Don't know what has happened but all of a sudden I'm
having two strange problems with Access 2002 (running on
Windows XP):

1. I can't view the Toolbox in form design mode. Click it
and nothing happens.

2. Clicking a subject in Help produces the following error:
"A runtime error has occurred. Line 114. Error: Operation
is not allowed when object is closed."

We've tried uninstalling Office and reinstalling, to no
avail. All updates/service packs are installed.

Any advise ASAP will be appreciated!
