VMware snapshot state is not saved at reboot

I'm using VMware Fusion 5.0.3.  I have a saved snapshot of a Win 7 VM.  Every time I reboot it, information that had been saved is lost and the snapshot is restored to its initial state.  I have taken additional snapshots, however at reboot of the VM all saved info (such as documents, settings inside of the VM) is lost.  Any ideas why this is and how to correct it?  Thanks.
