Zhann, Like I said, some graphics cards use your hard drive space to help bryce along. If you have done a lot of work in bryce and reboot, and still don't get your presets back, chances are that you need to do a defrag to your hard drive. Even a re-install, unless you un-install the previous bryce will use the same presets that are allready on the system. You said it yourself to Lin that the presets were in the folder, but bryce wasn't finding them. There are plenty of ways of fixing the problem without a re-install unless you are using a mac.
