No Memory Card Error Message--
Here's a bug with that Micro SD Card. Unless perfectly inserted, that Micro SD Card doesn't seat right and one will get an error message. I have dual M-10s, and had no problem, except for my second one, when trying to insert and enable cross-memory recording. Getting it perfectly inserted took about 30 minutes. It has a tendancy to want to go in at an angle, so pushing the card in from the entire back side surface, with a fingernail or pencil eraser seems to work.
If you look close under a good light, you'll want to look for one corner higher than the other. It will still click in, but it isn't seated right. Keep trying.
