Hello!!!
As i thougth, the save files has been overwrited the last time I opened the game (looking the modification date on Windows) and lose all the saved games. When I was installing all the programs/games again I moved all the files from the aux. hard disk to my PC, instead of copy/paste, so I don't have option to recover the files....
When I was configuring the save file on the cloud the fist time I think I press the option "yes, this device only"...
Time to start a new adventure, this time log in with my mail.
Thanks for take your time and GL in the next update.
