DK Digital mp-051



[qanda]This thread is about the DK digital MP-051. Click here to see full specs[/qanda]Hi. I have a problem with deleting stuff from my player.
I had some powerpoint-presentations on it and deleted them. They are not shown in the explorer any more but the space is used up.
There’s also a problem with the volume-control: Whenever I switch it to over 27 the Player goes “error”.
I don’t have any equipment or descriptions.
Is there any way I can, like, reset it or something?
Delete all of it and load the programs new?

Thx, Anya
