It says I have no memory..

I've had an MPC for around 2 monthes and It's worked fine. I haven't used it for about a week until today. I set it up so the flashdrive or whatever was on my computer and deleted everything on there.. (Dragged it in the trash). Now it says I have no memory in my memory card on the MPC and I bought the 132 mb card a while ago. It says I have 0.0mb. I'm really confused and need help..

Please help

Try to format your Compact Flash. And its probably 128mb. Not sure if they make a 132.

I'm not like a stupid person but how do I format it

may sound silly....
but did you empty the trash? if not, all the data is still on there.
