Please check to see if "Do not save auto-recover info" under Large Assemblies is checked in Tools, Options, System Options, Assemblies. There was a problem with the panel not showing up when that options was checked and this problem was fixed in 2013 SP05 and later.
I hope this helps,

When my version of Solidworks crashes, auto-recover doesn't initiate on restart. The auto-recovery directory is empty. I attempt to use auto-recovery, but in typical Dessault fashion, the feature is broken and remains so for years.
