Maybe you need to upgrade to a newer version?
Mine started doing that and then was followed with a message that my hard drive was defective. I am on a borrowed computer -- mine is getting a new hard drive. Tech seemed to think the Flash-drive crashing was the first symptom. Hope that is not true for your system. I have a laptop.
if it is Adobe then that explains it. If it isn't adobe then I don't know!
All pornedddd out
