I'm using Access 2003 and my queries have never failed me before, I've run the same ones for the past year now without any problems. Now today all of a sudden I can't even view the queries in Design Mode. I get an "Invalid Argument" error. I can't even refresh my linked tables (linked through ODBC), I get another error similar to the Invalid Argument. All I want to do is run these queries. Does anyone have any suggestions? I've resorted to redoing the entire DB, but I wanted to copy at least one of the queries to use.
