I did go back and reset the control panel preferences following the PT LE suggested configuration (memory allocation, no sleep etc). I also reinstalled Reaktor so I am pretty sure that at least PT and Reaktor have the settings straight. Also I currently have very few programs running on my machine and no internet connection...

Do I need to go through each item in the control panel and set it back up? what should I do to remedy this mess?

Thanks for your help
