Default [Q] Recover lost contacts

I installed kitkat 4.4.4. from cynogenmod on my xperia l. Before doing i made a back up of my call log smses and contacts using super backup pro. I had changed the back up path to external memory but somehow i think it got backed up on internal memory bcoz i cant find it on the memory card. I have formatted my internal memory. Is there any software or method to recover my contacts atleast?????
