Took a ton of pictures today on vacation.  I was able to view them on the camera itself after taking them.  Got home, put memory card in my computer, pictures weren't there.  Put memory card back in camera, pictures were gone from there too.  What the heck?!

I tried running a data recovery tool to no avail.  The files it found for me were all old pics.  Nothing from today's date so I did not pay the money to recover them.  All pictures from yesterday and before are still there.

There IS a .ctg file with today's date on it.  But the pics themselves are gone.  Is all hope lost?  Is there a better recovery tool to try (used Stellar data recovery tool).

ETA: Camera is a Canon EOS Rebel T3i and memory card is PNY Elite Performance 32GB SDHC.
