Data base "ghost" path not found - any one knows such a prob?

Hi,
I am writing an app that usses a data base witch is an access mdb file.
When i have changed the database, i made a new file (ver1 and ver2 of the same datavase), both files where in the same directory and evry thing woked fine.
Now, when i deleted the old database file, since i dont use it any how, i get a vb msg that said it cant find that first file - but it hapends just in an end of a function - while there is no use of this path what so ever in the whole project.
Apart from the msg - the app works fine.
Any one knows what this could be?

Thanx
Dani
