Up until last week, the Crystal Reports section of my application was working fine. I have four separate reports, all linked to the same database, and they did what they were supposed to do when told to do it.

Then, one of the four reports began to malfunction. The others still work fine, mind you. It began to give me an error message that said "Error in file links. Warning: Fields in the report from the file 'Device' cannot be linked." Device is one of the tables in the database I am using. Now it gives me an error message for every table in the report except for the first table used. The fields from the other tables are not populated when I run the report.

The really strange thing is that the report previews fine in Crystal Reports. I checked all the database properties in this report against the other reports, and there are no differences. I am completely stumped. Does anybody have any idea what is going on here?

Thanks,
Jonathan
