... and I'm back again

.
I've been trying to use this software to write an image to a MicroSD card: two (2) of 'em, actually, a one (1) Gig SanDisk and an eight Gig SanDisk. Every time I try, with either card, the software comes back to me with a message that the target has insufficient capacity

. The image file I'm trying to write is only 124+ Meg

. I've tried several forae with no result, and none of my searches have displayed an error of this nature ... so I'm back here again.
Oh, if it matters, I'm doing this to play with my new NookColor
