Every time I take a picture with my new Curve it says, "Ciphering material does not match this device." Starting to get very very frustrating because I can't save any thing. I have my BB set up to save all pictures to my 2Gb SD card.
I couldn't find anything in this or other forums either.
Your problem is a security feature that was enabled on the original device. If you put the card back in the original phone, then from the home screen go to Options -> Media Card -> (then the second option is "Encryption Mode") change that to None.
Now when you install it in the new device, it will have access rights to the card. You can, of course, re-implement the the security in the same manner.
