Sorry for getting out of the topic here. I think though that has to do with the configuration of the Oleds from 4d so it would be helpful for everyone.

What happend to me is, when i format it, it doesnt like to write the graphic composer on the uSD.

I took the uSD out of the computer port and then i placed it back. Windows asked me to format the card. I just pressed cancel.

Then i opened the program again and i tried to send a picture. It was ok then and it seems that the file sent to the card.

But i cannot see what is happening to the card since is not formatted.

I will try to buy an other uSD and i will also try a windows XP computer and let you all know.

thanks for your help.
