Here is some ideas. If your using ATI then your Control suite is limited to run low GUI rendering, if your using Intel then go to www.intel.com and use the auto detect service in your browser to find the correct driver, If you using NVidia also route to their site www.nvidia.com and use the auto detect tool. If you have ever ran Sl on your OS computer your currently trying now then best suggestive idea is that your runing the wrong kernel driver for your device. Now depending on the Operating system your running Linux, Windows, or iMAC is how you install the correct driver. If you recently install the newest driver and tried SL right after that driver install then maybe you should reboot PC. Might I ask what Operating service are you using " examples " Windows xp, vista, 7, 8 / Linux distros 32/64 bits KDE, or iMAC 11? If you use one of the earlyer ideas of the auto detect service from your graphics driver providers website and the site found a newer driver> then download the driver and save to desktop for easy finding> remove the older driver from your system then reboot> as return from boot you can then install the newest driver will your OS is finding driver files. If still a issue then your possible not able to run Sl in the 3D render since not supported on your GPU, or your stuck in a bug and should submit a support ticket VIA the ticket channels.
I try to help, but I'm not always right. I am determined to keep trying to until its corrected. So success always appears.
