mtu not reconizing my plexwriter drive

[shanold1]

When I ckick on the micro icon it loads but does not reconize the cd rom drives. I do not know why this happens I have used it literrly hundres of times. I tried restarting my coumputer and it still did not reconize the drive when I check the cd rom properties it says the device is working properly. I've had this problem before and had to use the system restore to an earlier time but I don't want to have to keep doing that.
Need help in Albany.
