Thanks for the reply.
So if i understand correctly the Plextools is the one for me to instal and not the Kprobe.
Final q'n, yesterday Plextor tells me that when i instal Plextools Professional this is free, but Plextoos Professional XL should be paid for.
I like the fact that i can check my discs like in the XL version wich the non XL version doesn't have so many options.
Any adivce what to do?
