yeah--the last several versions (past 2 or 3 years, I think) have been very problematic. The software developer doesn't have a CS/P2500. I have up years ago after having spend hours testing early versions and giving him feedback. Yes, its a shame, but there's still proteum. The last time I looked, that never didn't work with CS/P2500s. I cannot say that about prodatum.Sometimes you get what you pay for; sometimes you get more. ;-)

PS: the last version that worked with my P2500 was zero point something.
