The software may be good, but the developers are terribles and suffer from paranoia.

I paid a lot to use this software once, and I didn't use it for months. They decided to ban my licence without any reason, and try to force me to upgrade. I sent many tickets, no answers ... And I cannot use the software at all ! Several hundred dollars to use a software one time !

I leave comments on their FAQ (I was not alone in this case), they deleted the topic because of all the negative comments. They have time for this, but not for answering support tickets.

I never saw any company handle customers this way !
Pass you way, it's extorsion. Get any other softwares, but don't give money to theses guys, they have a serious commercial problem.
