stylish error when installing codes

ok back now! tried all that ( cc cleaner) no good ,still getting error message!
bummer i really like the google dark grey style

hey reg hello again,ok d'y recon its a firefox issue and not a stylish issue. ive got heaps of add ons installed and will be a nightmare sorting it out . perhaps a project when i have more time to spend on it

thanks!

AAAAHHHHH! completely uninstalled firefox and all registry bumf , reinstalled ff, it some how had all my settings ,add ons , bookmarks the lot , so im thinking i cocked up somehow ,retried stylish still error message . may have to give it a miss .fek!
