So if anybody has a similar problem, the answer is, to change OS ( in my case, I did to the 3.0, with the 3.1 I had still a little trouble, ) it works great, no more "warning flash RAM formating" or check sum error", etc. I uploaded the styles/patterns, made my registrations, no problem anymore, thanks to the guys that answer with suggestions/advise, they put me in the righ track.

P.S. I really like this Forum !! Great Job
