Recovering from hard drive fail

I had a hard drive fail, managed to recover with software the files in the hard drive, this happened after December 17 so I assume I had the latest version of the email client.
I installed it again, copied all the folders to the new client and the program crashes, this is the message I get:  (I need to recover most emails but most important my contacts)
