Many beleive it never DID work! It was the first software package advertised as a 3rd party product for the HP-1 and Butel had stated at that time that we was NOT going to offer a product. So, in desperation, I like some others bought from ScanCat. IMHOP it was a waste of time/money, was poorly ducumnted, not supported and brodered on being a 'rip off'. I imply wrote it off as a mistake, when ARC Patrol was announced I bought it in 'beta' and, as I expected, fully met my expections.
