This error was being produced when trying to load small FDB (Legacy) files. Fixed in Version 1005.
Trial users can get that version at www.gensmarts.com/download.asp, you may need to "refresh (F5, or View...Refresh...)" is you don't see version 188.8.131.52 listed on that page.
Registered users will receive the update automatically over the next day or two (if you need it sooner, just drop us a note at firstname.lastname@example.org).
