There might be set of reasons...
I'd start from recovery mentioned by Guru of MS Access - Allen Browne, see:
Microsoft Access tips: Recovering from corruption[
^]
At
this forum[
^] was stated: "
IT modified my Group Policy, and the problem has been rectified.
". So, check it out if it fix an error in your case.
When none of above won't help, this post might be useful:
On error resume next stopped working[
^] (this post was made based on my experience).
The last - but the most important - note: Stop using MS Access file as a user interface. Rather than it, use
WinForms[
^] with
ADO.NET[
^].
Good luck!
