Well, like the title says, what are the limitations on the trial version except it works for 30 days only?
Also, what version is it? Is it the Lite, Extra,Commercial, Pro?

not to sound rude, but you should probably read all the stuff under the feature list before you ask questions on the forum : http://www.conitec.net/english/gstudio/order7.php

The trial is Pro AFAIK, but with some limitations. You'll get a text about it when installing the trial.

I did read the feature list but I must have missed the trial mode function.

Tobias thanks, that should be more than I need, I was hoping it was at least higher than the lite-c full.

Installation gave me the following information:
The trial version runs for 30 days, does not allow to publish and limits the runtime of the engine to ~5 minutes at a time. After ~5 minutes it pops up a message that you have to restart the engine.

All in all more than enough to try it out.

I read somewhere that the trial is the extra with shader support, but I also have heard it's the pro without massive multiplayer and of course without compile-to-exe...
Maybe one of the developers can answer this question.
