Can't Read or burns cd's with microstudio v3.312 in winXP

[nestorpadron]

I can't read or burn karaoke cd's with microstudio v3.312. The problem is that when i try to select the cd room drive to read or burn, nothing comes out, i mean, i cant select the recorder o burner, which is a plextor.
These problem began after resetting my computer because i had troubles with some virus, and then when i instaled the software again it didn't work. I can run the program and play songs that i have in my hard disc, but i cant read the cd's with karaoke songs.
I dont know what i have to do, i dont know if is some problem with the Windows XP.

Thanks for your help
