pandigital planet questions

[m987]

Hi i have several questions. first, when I enter the sd card that comes with my tablet to my pc shows two things, removable disk and something else i do not remember the name (where the gallery and musics is). That something does not appear anymore. Now the gallery saves only one picture and music does not show anything. Second, android market does not download anything and says i do not have any device. Third, this frase always appears, " the android process media has stopped unexpectedly." Finally how do i download books? Please help me. thank you
