So it looks like that one picture was corrupt. I think PCs stops copying when it encounters a corrupt file. When I encounter this, not with memory card, but PC is general, I usually skip one file and try the rest.
I wouldn't worry about the walkie talkie though. I doubt that's the problem.
The format that cameras do is nothing more than erasing the FAT table and creating a new one. So try doing a full format with your PC, or better yet, do a scan disk on it also.
