Cannot access RS MMC card

Hi all,

I have one RS-MMC card and I having problem to access the card now. I think I had accidently lock it but I forget the password and I cannot access the card via my card reader.

When I double-click the drive of the card reader on my PC, it popup a message sound "Please insert a disk into drive E:."

Anyone can help me on access th RS-MMC or suggest any software that can solve my problem?

I will appreciate for you input here. Thanks.
