Had Reaper working nicely for a while, no problems whatsoever except for occaisional crashes. Now.. all of a suddent it takes 2-3mins to load a project, crashes constantly, tells me theres CFD errors (not enough memory to load tracks), makes glitching sounds, the interface lags to high heaven and I can't render anything. As far as I know, I hadn't changed a single setting. Under CPU usage its at ~55%. I've closed down all background programs and its the same, I've rolled back to an older version and its the same. Any settings I can use inside reaper to minimize this memory usage or find the cause of the problem? Is there a way to revert to default settings? Perhaps this is an ASIO buffer/setting issue? Any help much appreciated.
