You need to bring the card back to its original settings now. As far as I can tell the data is lost, so no use crying over spilled milk at this point in time.
You have two options to do this, there is no other way that I know off hand, so if it is not possible with your PC or items, find someone who has the ability to do it for you.
Option (A): Get a SD Card adapter for your (or someone elses) computer, connect the card, and format it as you normally would to bring it back to factory settings
Option (B): Find a digital camera, insert the SD card, and format it through the cameras options (most cameras can do this for you)
Option (X): Get over it and buy another 4GB card as I believe they cost like $5?
