Hey Man,
I've used their shit for a while - their customer service SUCKS ASS, it always has. The only decent one there is Mike Zhang MSN:
[email protected] email: Mike AT topcmm DOT com
The rest only have the stock answer "email support" or "I don't know"
If you just got v8.0 then I also pity you, I upgraded and had like 3 days of hell while every memeber pointed out a list of bugs and had to downgrade again to v7.5
Once you get it set up and intergrated it works okay, just when its running don't touch it or upgrade ;-)
Oh yeah, I've had the licence thing too, did you try to reinstall on teh same machine when you ran into issues or reapply the licence? Thats what did it for me - it was liek national holiday in China for something, I had to wait days running in demo mode.
Heh, did I mention, their customer support SUCKS ASS!
