FLASH CARD KEEPS ERASING :?:

Every so often now, my flash card keeps eraseing or becoming corrupted-like i will turn the machine on and there will be nothing on my card. and then I have to re format it; over and over again. its a surprise everytime. so should i get another card? should i change my OS? (JJ OS 3.08). My card is a JAMedia( Delkin devices) 2G DDJAMCFPRO. sry if this has been said before, i can only get online every so often throughtout the busy day.

My card was playing up the other day bro and you know what it was it was one of the pins was bent inside the card slot on the MPC, have a looky in there you might have a bent pin I straightened mine up with a tweaked out paper clip and no drama's since then
