Max media Dock,something wierd is happening HELP!

Well uh just recently my MMD was freaking out.Let me explain:At a Wii60 party I formated the CF card I put on some mp3s,they played of course.But what was wierd was that the Mp3's were mixing with my DELETED video files,as in they started to play the audio in a video once the mp3 got to a certain point.And heres the most disturbing part........they played in squeeky vioces!!!

Anyhoo also my MMD isn't being reconized by my computer as in it won't pop up.I've tried again and again,nothing.Has anyone gone through what I'm going through?And if so....HELP!!!My MMD played movie files a while ago(like a week ago)But now I need to format it for the 6th time because it won't detect anything,and to make it worse my computer doesn't seem to see it either AKA I can't format the card again!!

So ya anyone know what to do?

So anyone........Know whats going on?
