If it makes any difference we running Version 6. No issues and then suddenly...

Hi All,
I am suddenly getting an error when nesting.
Once the file has been selected, I select Nest X or Y,
then a "RNest" error pops up saying:
Unreconized database format: \Rolling Nest\result.mdb

Anyone seen this before?
and any ideas on what can be done to fix it?

Thanks in advance,
Neal.
