[uxtheme.dll -> system crash!]

I there I wanted to use Watercolor 4.2 and the only way I knew how to do it was the w2k3 way.

but I downloaded this

http://www.msfn.org/modules.php?modid=2&action=show&id=75

by accident because I wanted this

http://www.msfn.org/modules.php?modid=2&action=show&id=89

I applied the first patch and now after reboot system refuses even come back

no safe mode,

no lask known settings,

no restore

all get stack at one point and self restart.

anyone had such a problem and if yes is there way to fix it or just reinstall will fix it all.
