MyMPx.org - HELP ME PLEASE

Ok i tell you what happened i have a 4gb clone nano player. It died because i instaled wrong firmware. I went throught the recovery guide but it did not help me. When i connect it to my pc it shows me 2 removable drives. But when i try formatining it sometimes it works sometimes it doesn't. The problam is that when i go to the upgrading tool it doesn't reconize that my player is connected. I tryied different mp3 utilities none of them work.
