I am under the impression that you've an installation problem, this is why I suggested to contact with the tech dept, so they can check the issues in your computer, installation, etc. In addition, they will check your system, limitations, etc.
Did you try to call them?
I sent a PM asking for assistance regarding the demo versions. Let's see if I can get an answer.
I am just a volunteer here, however, I will do my best to help. Few questions:
1 - Please include the title, version, and platform you are using. It is important to mention the exact name of the program as well as the version number (yes, I need both). On the PC you will find this info in the main menu->Help->About… On the Mac this info is on the title menu->About…
2 - Some issues can be related to hardware you are using. Please post any information you have on your system (operating system, processor, video card, etc).
3 - What happens if you press "F1" (with the program opened)?
