Problem w/ Sony DRU500ulx and RNM V.4.5

[brkr101]

I'm having a problem making any backups (primarily PS2) using Sony DRU500ULX, Record Now Max and 4x Media (tried Ritek and Princo). My Sony drive is not detecting or recognizing the blank media...keeps spitting it out and saying "insert blank media". I had this problem about a year ago...downloaded latest driver and it seemed to fix it...but not this time. I been working on this for about the past 5 hours now...any suggestions?
