André,
I have a problem that is similar to what's described in the original post.
in my case, the VM starts successfully when Snapshot #5 is selected; however, any attempts to select #6 (mdServer-000006.vmdk) or #7 (mdServer-000007.vmdk) result in the same "The system cannot find the file specified" message.
I would really appreciate if you could help me in recovering the latest snapshots.
The attached zip contains all files assembled per your instructions.
Thanks,
Vitaly
