I tested the Windows version of your app and here's what I found:
The TurboActivate.dat file you're including with your product has the "Trial days" set to 0. Set the correct amount in LimeLM, download the new TurboActivate.dat, then include that TurboActivate.dat in your product.
Does that make sense?
You also have one other unrelated problem that you should probably fix. When your app is not activated the "MeetPro" menu has a "DeActivate" menu instead of an "Activate" menu. You obviously want the user to activate when they're not activated.
