I am running Win7 64 bit and sometimes everything works ok. Other times I get an error 'CEP Service Manager has stopped working'. I close the app then a few seconds later it comes back. I just processed around 30 RAW images and I must have had to click on the error at least 40 or 50 times. Can anyone help with a solution. I have not been able to figure out what triggers the error or why it works sometimes and not others.
