I have downloaded HUD yellow icon pack. I have installed it using the 7stp gui. When the computer restarted there is a black screen and I can only see my mouse cursor. The is nothing there. I restarted in safe mode and same thing just a black screen and mouse cursor. I manually created a restore point before the gui did a restore point, and I backed up all files said in Mr. Grims warning. I can not get to them since there is nothing to look at. Help please.

I am running windows 7 x64. I7 2600 processor with Geforce 550 Ti graphics card.
