Can't download Microstudio Software

[oklahomagal]

Yes I did get Microstudio to download, however I CAN'T GET MY BURNER THAT I BOUGHT FROM YOU TO DOWNLOAD. WHEN I LOOK IN ADD/REMOVE PROGRAMS IT IS THERE, BUT ON MY COMPUTER IT IS NOT SHOWING A DRIVE. IT ONLY SHOWS DRIVES A: FLOPPY
C:HARD DRIVE
N: CD ROM

NO DRIVE FOR PLEXTOR......IT DOES RENAME THE N DRIVE TO PLEXTOR, BUT IT IS ACTUALLY MY CDROM DRIVE...PLEASE SOMEONE HELP....I HAVE BEEN UP PAST MIDNIGHT THE PAST THREE NIGHTS TRYING TO FIGURE IT OUT!!

THANKS!!!!!!
