Okay, that is the obvious end goal however right now you have a VM that's not functioning, has as snapshot that cannot be removed due to it base disk size and snapshot disk size and the amount of free space on the volume it resides! So I can tell you how to quickly get it up an running but that doesn't fix the cause of the issue and will leave the VM with an Orphaned Snapshot State and that isn't necessarily a good thing under the circumstances.
So do you what to just get it running or do you want to consolidate the Snapshot and get it running?
If all you want to do is get it running then just delete the "Mac OS X 10.8 64-bit.vmsd" file which will get you past the "File not found: Mac OS X 10.8 64-bit-Snapshot2.vmsn"error message and completely orphan the "Virtual Disk 2-000001.vmdk" snapshot, which is effectively orphaned anyway because the "Mac OS X 10.8 64-bit-Snapshot2.vmsn" file is missing and not within the Virtual Machine Package.
If you want to fix it so going forward you are starting with everything in on .vmdk or split into 2 GB max Extents where you will have a lessor Host free space overhead requirement when working with Snapshots then this requires much more then the "just get it running" approach!
