Oh dear - thats 5 years ago - sorry I dont remember any details.
All I can say is that your do not have the same issue.
Your case may be trivial - maybe just a missing descriptor-vmdk or a syntax error.
So if you want help provide a list of all files in the VMs directory - to create such a list use ssh and putty and run
ls -lah > filelist.txt
or create a screenshot of the display in WinSCP.
Make sure the list includes the full filenames, filesize and filedates for all objects.
