You can easily recover data from memory card. I had deleted our honeymoon trip pictures mistakenly, and then my husband gave me a good scolding. I was upset that day. I googled and found an amazing software by stellar data recovery services that gave me back all my honeymoon pics. Sigh!!
Well, as long as your data hasn't been overwritten, there is a great chance to recover your pictures. Try Jihosoft Photo Recovery. It works for me. Good luck!
