That all being said, to get the most out of this extension you should expect to pay for support. Especially when involving complicated configurations - just common sense.
Maybe they should make it commercial so people don't get mad that they can't handle a more advanced component than they're accustomed to and give it a bad rating.
Thanks for the flowers, but I will have to correct you here - Our reviews got deleted because we DID switch to commercial.
I would further say that you don't need to expect to pay for support, but for some configurations, it won't hurt.
Let's put it this way: AEC can be complicated and if you want to prevent a headache, there is a cost for that - our support. Some of the bad reviews in here do stem from people just getting frustrated with the software and then blame us for offering support. The upcoming manual and mandatory base support for fresh AEC users will hopefully make up for most of this ;-)
Anyways - thanks!
I have yet to contact support simply because I have lacked the need to, but I have accessed the crosstec forums for tips/tricks and overall usability.
I will be using this extension for multiple sites in the future thereby outweighing the small investment.
