1. In order to activate / register you must have purchased a serial number. The serial number looks something like "00018-7G4D9ABD0D1J”. A serial number will only activate a product on a single computer. If you wish to use multiple computers you must purchase multiple serial numbers.
2. Open the Somatic Vision Product Activation by going to Start Menu->Programs->Inner Tube->Activate Inner Tube (or if the trial has ended just press "Yes" to activate when asked to activate).
3. Enter the serial number in the "Product Serial Number" box.
4. The product name, computer code and product status will all automatically fill in when you enter a valid serial number.
5. Click the button "www.somaticvision.com/registration/" to register on line with this computer. If the computer you are using does not have internet access you will need to write down the computer code and serial number, go to another computer (with internet), and go to "www.somaticvision.com/registration".
6. Enter your details and press "Unlock Product". Write down the unlock code you receive.
7. Enter the unlock code into the "Enter unlock code" section of the Somatic Vision Product Activation and press "Submit Activation". Make sure to enter the unlock code into the one computer you want to unlock (if you got the code using another computer’s internet access switch back to the original computer to enter the unlock code).

Complex real-time 3D games are generally required to be run on the monitor set as your "Primary" monitor. If you have a fast enough system (Pentium IV 3 Ghz) with a good recent ATI or NVIDIA system it may run well even on the secondary monitor.

You can either try lowering the resolution of your secondary monitor or switching the primary and secondary monitors. You can also drag the taskbar and icons to your secondary monitor after you switch which is your primary and which is your secondary monitor.
