My friend got a MP4 player and we tried to put more songs to it. The player also acts like a flash drive. The songs were already there in the player but she can't play it. We tried to delete the files but it would reappear again. IT went that way all the time, it seems that we can delete it now but in a few seconds it is there again. We also tried to click "My Computer" on her desktop but it says "Not a valid window 32 application" and when we clicked it again, there's something that popped out and tried to install something. We used the Task Manager but we cannot open it, as well as the regedit. What seems to be the root of the problem here? ANy solutions? Thanks a lot in advance.
