blue screen after installing evilnat cex 4.90

so after a long time i decided to install evinat cex 4.90 over the pex 4.90. had some troubles with games not opening and wanted to try if it's any better with cex. big mistake i think. after installing the cex now all in get is a blue screen. that's it. the ps3 turns on fine with only the green light on and at first the hdd indicator light is also blinking. when i try to start it in safe mode the same thing. blue screen.

oh and i also cannot turn it of. if i press the power button nothing...
