Just another CPA here replying to your message - we've all **bleep**ed and complained about ProSeries for various reasons, but I'm not aware of anyone else who has had the problems that you have had. 

Considering 50,000+ tax preparers use this program I wonder if any of the issues you're having is coming from your own computer system.  For example - updates not fully installing. 

Yes, we've heard of problems with billing, canceling and renewals, but again, rare to hear what you're encountering.  Wish you the best with whatever software you choose next, and please - come back to this board a year from now and update us all on the new software, ease of transition, etc.
