I've rented a routing/scheduling program for my business for some 5 years before finally buying the dang thing.  Now I am trying to install it on my laptop which has Windows 7 and i get an error message.  Since I am 9 days out of my annual update subscription they won't help me without my renewing the annual updates for a mere $350.   
What gripes my rear about the program as well is that after I bought the program I found out that I have to have the programmers permission to use the damn thing through their password verification.  And they wonder why I don't want to renew my updates.   
Aaarggghh!
