I have never seen this error before, so let's make sure you are using the right programs & files first.
Did you initially install the 'full' Catobase program (with MDAC and other required files - about a 10 MB install file)?
What version of OOTP are the files you are using coming from?
What version of Catobase are you using?
Are you using the correct CommishJoe CSV Exporter from Jeff Cato's site (
www.jcato.net)?
