If you're using windows vista or 7, click the start bar -> click "computer" -> you should see a list of drives. One of them should be your SD card. Right click it, and click "properties". From there, you should be able to tell what format your SD card is in.To be completely honest, I have no idea what you mean by format of SD card.
Now that I think about it, though, I don't think that having it in the wrong format would do something like what is happening when you try to load PM. I'd say just re-download the pack and try again.
