Database Results Error

I've created a database using the DB results wizard in
FP2002. Everything has been great for some weeks, now
all of a sudden when I try and look at the database
editor, I get the message shown below in place of any
data:

Database Results Error
The operation failed. If this continues, please contact
your server administrator.

Has anybody come across this before and know what to do
to resolve it?

Thanks in advance

Steve
