I had to delete 3 images while in Charleston last week.

Anyway trying to get them back now. It is not a sandisk card and that software that I have and it says it can't read the card. Any suggestions on a good software?
And is it even worth trying cause I shot about 50 more images after they were deleted? There is plenty of space on the card but there doesn't appear to be any breaks in the #s so I guess I have it set to continue on with out remembering that something was delete.
Any way my question is is it worth trying to recover the 3 images or not?
TIA
