Just wanted to add to this topic: I'm also getting incredibly frequent crashes with Reaper (3.0 and 3.01) - I had no problems with Reaper 2.58 at all - very stable today reaper crashed every time I pressed 'play' - i seem to remember the error report mentioned ntdll.dll (but not sure if i remember right) and the project i was running had only a few audio tracks and a few VST effects - nothing to stress the system will get more info/error reports if useful to anyone...? meanwhile considering rolling back to reaper 2
