NEC 2500A Burns but no longer reads/recognize ANYTHING!

My NEC 2500A which worked fine for a month with very low usage since the one not working is on another pc. Anyhow now it suddenly just stopped recognizing discs. It just says please insert disc into drive “X.” This happened without any changes and no reboot since the last time it worked. I am really stumped as to what the problem is. What is really weird is that Nero will burn CDR and DVDR on it but again it doesnt recognize any disk I put in it like when I go to My Computer and click on the drive, etc. Please help. thank you

Nevermind I solved the problem. Apparently Paragon CD Rom emulator got screwed up or something else did and my drive didnt have a letter anymore but a virtual drive did instead. WEIRD
