I recommend checking the support articles to see if one fits your particular needs. For example, http://support.spacetimestudios.com/...rticles/963871 talks about updating graphics drivers. If none of the articles help, you can contact the support team for further assistance by clicking on 'Contact Us' or emailing support@spacetimestudios.com!

I have gone ahead and moved this thread to the PL Technical Issues and Bugs portion of the forums.
