That "out of ram" error is a generic error message and doesn't really mean your out of ram. Try deleting your pic cache and defrag your hard drive. Make sure you do not have allot of programs running in the background in your device manager. If you are in 64bit, load up some ram, if your not, use the 3 gig switch
If that doesn't help you, then it MUST be your SB Live Card. heheheehehe
