I have problems with formatting MMC-Cards:

After formatting the MMC-card in the Phone my software is not longer able to access the email-MTM.
If I remove the card an replace it by another one (eg from a other Phone) the softwae is working.

My software in NOT installed on a MMC-Card and does NOT use any component located on a MMC Card. Email-Profile is NOT located on the MMC-Card. Sending Emails with the Standard OS-Interface is possible.

I use a Siemens SX1, but I had similar problems on a Nokia 3660.

I dont have a clue, can somebody help?
