Cannot log in to user acount after time-machine restore

Hi guys.

I had a damaged secondary hard drive (instead of the superdrive) in my macbook pro mid 2012. My technician removed it.Before he did, after disk verification that I did, when I tried rebooting, I got a screen (attached) saying I cannot log in to my user acount. The weird thing is after my technician removed the damaged secondary hard disk (leaving me with a 240 SSD in the normal location) AND installing a fresh and working yosemite, I did "restore from time-maching" from the recovery mode, and THEN got the same annoying screen that I can't log in.

I understand that the backup is damaged or something but I just can't log into yosemite even after installing yosemite again from the recovey mode.

What can I do?!
