Android Question

I'm not what anyone would call overly phone savvy, but I did a little research and decided to make room on my HTC Rhyme I would encrypt my SD card and move some files and data to that. What ended up happening is that now all my photos are gone and I don't know how to access my SD card to see if they are on there. I've tried a recovery program but that didn't seem to work and I'm not sure if that's because my device isn't compatible or maybe there aren't any files to be found. Any words of wisdom?
