Hi there, I'm very very glad to hear your mp4 is back to life. That thing (deleting the characters) I knew it from my own experience. Unfortunately I don't really know how to fix the button problem....I haven't run into that (yet) because my player is still dead
. Try asking admin or tadad or people who really know what they're doing....I'm still a rookie in this business and all I know is from my own mistakes
. Good luck
