A few things that may help.
1. Making sure your drivers are up to date, especially your graphics card driver. You can also downgrade your cards driver just to check.
2. Getting a key is easy, just send a support ticket and you'll get a key within a workday. I added my order number from mycommerce to be sure. The FilterForge support team is one of the best, I've asked them for help numerous times. Sry for so many questions.
