Deepfreeze trouble

I recently removed deepfreeze standard force fully with changing cmos date and removed the original file from c: by disabling it from task manager and i even cleared reg in hk machine it worked for just one run. after i tried to make any changes in my laptop it remains still untill i restart or shut down my pc.
If i try to start my pc at that time it remains as it was before, i even try to reinstall deepfreeze again but it says"Deep freeze standard must be disable before any install\unistall can procced". thou i have already erased everything releted to df so i m screwed up with ths problem it would be great help for me if you give a proper solution for this problem.
