Burned CD will not open!

Hey,

I created a data CD on EZ CD Creator that would only open on my DVD drive, and not my burner drive.  When in my burner drive, windows tells me that the volumes on the CD "cannot be mounted".  To fix this problem, I tried closing the CD in EZ CD Creator, and now the CD won't open in either drive! help!  Can my CD be salvaged somehow?

Thanks for the help,
Greg P.
