whenever i try to start logic 5.5.1 (for windows) it'll go through the standard load screen but when it gets to loading external sampler communication logic crashes. ive had logic for about 2 years now and every once in a while it'd do this but today its been doing it every time ive tried to load it. ive rebooted and shut my computer down and nothing will make it load. anyone have any ideas on how to resolve this?
