SD card not recognised

[Karma-lite]

Hi
I'm using the MP3 player and it sort of works
I've got a san disk SD card and this works fine.
I also have a Kingston SD micro (n95) but when used with an adapter the MP3 player says there is a card error......any ideas?
Cheers

Woah....
Need to be alittle more specific.
1. What MP3 player?
2. Are you sure the San Disk SD card works?
3. Are you sure you are in the right forum?
