Not Reconizing Drives

[kenn1245]

I've just updated to Microstudio 2.508 from 2.314. I've updated my adapdec drivers (solutions #1, #2). I've update my windows xp home with the lastest updates, I've rebooted, I've changed to defaut driver under drivers, I've closed, I've reopened, I've rebooted again, I've changed a few of my hairs to gray (not a mtu problem), still can not reconize my hp serious 9100 cd drive or my samsung cd drive as before.
Help Please.
I've look through all the posts, couldn't find a previous problem.

Thanks, Kenn
