Hello,
One year ago I made a mistake of enable the ATI Center option in the DP G-A, without the .NET. 
I got to desinstall the driver, install the .NET's, and reinstall the driver again to fix it.
My PC was a PB5 ASUS P4 3.6GHz with a ATI X1900XT .

Last week my Motherboard passed away, rest in peace ... we have such a good times !!!!

Now I build a P5K with a E8400 Core DUO, and the old ATI X1900XT.

This time I tried the Control Panel option, and I got now the "not enough memory for this task" issue.
Reinstall the last version didn't worked, but disable the control panel in the msconfig yes.

Anybody knows how to enable the CP again ?
If not I gonna try desisntall and install the NETs and the Control Center Version ...
