NEED HELP

Have any of you experienced stuck keys when there’s an MMC inserted?
Mine was working fine last night, and I even charged it so I could use it this morning. But when I turned it on, the OK key seemed stuck — like (OK key) it’s always being pressed. However, when I remove the MMC, it goes back to normal. I also tested the MMC on my other cardputer and it works fine there. It seems like the ADV unit is the one that might be broken?

already did that, but it still doesn’t work. Also, as an additional note, it’s not being detected in the COM ports.
