Error: Media not found using Copy2DVD

I recently purchased a system to use as my burning machine/burning station. :wink:

Its an Athlon 2000+, 512MB ram, Asus A7N8X mainboard, Geforce 3 TI500 video, Soundblaster Live audio. Great little box, doing the job fine, until yesterday.

I’ve been able to burn multiple discs with this machine so far, but out of the blue, I’m getting this annoying error message when I try to burn with Copy2DVD that states there’s no Media in the drive, and to please insert a blank or (re)writable disc - despite the fact there is one there waiting for it.

Using Fujifilm 4x DVD+R’s, burner is a Pioneer 106D.
