Probably the wrong news group.
Go to the VBE (VB Editor) - Alt F11 for Access version 2000 and later.
Go to Tools, choose References.
There you will find the culprit.
Removing the broken reference will stop the error message but the
control will obviously no longer work.
If you can find the control on your system (you can use the Start, Find
facility to search for the file name) you can fix it so the database
works on your PC. If it is a multiuser database, used on several PC's,
you will potentially break the database for other users. In that case,
ensure that every user has the file in the same place.
Hope that helps,
