I think my nic is the cause of bt crashing my system. I don't think it handles simultaneous uploads and downloads very well....I can max out either separately but when I up/download at the same time it crashes.
But the FLAC issue I've had NO luck on.
Both of these problems result in bsod. FLAC crashes in every version... grrrr....
...guess I'll have to continue to use mkwACT...
