Feurio pbs


I used to burn dics with Feurio! since two years, everthing worked fine.
I’ve had to re-install xp and my programs some weeks ago, and using Feurio CD Manager, I always have this message when introducing the blank disc in my writer:
" errors reading the directory cd" .
Any help to sort this out ??

Another question is : would my cd be faulty if I burn it with these errors reading directory?

Thanks in advance for the help…
