missing or broken reference error

[MorningStarFan]

Hello. We have an access db out on a shared drive that is giving this error
from a form our end-users use to enter data:
Your Microsoft Office Access database or project contains a missing or
broken reference to the file '4TWDLN10.MDA'.
When we look at the references in design view it gives this path for that
reference
C:\4TOPS\4TWDLN10.MDA
On Google there was information indicating that this is and add-on...
Can anyone tell me if this is a legitimate MS add-on? If I remove it the
form seems to work fine.
Thanks!

Doesn't sound like it's from Microsoft to me.
