Primedisc 40x with Liteon LTR-48126s

Hey all!
I have bought Primedisc ( made by ritek) 40x CD-R 80.
I’m using af Liteon LTR-48126s firmware V2S0D.
I have managed to burn 4 disc’s, but now my CD-RW can’t detect the disks!!!
Is this normal for the combination of CD-R and Liteon…?
I hope not, I have 96 disc’s left :wink:
