Unable to Obtain Hardware Information For The Selected Machine

It's been a long, hard struggle to get this far, but now that I have successfully installed the ESXi Hypervisor on my powerful Dell T710 Server, I am not able to convert the thousands of hours worth of Virtual Machines that I've built using VMware Workstation 7/8. 

I've read countless articles/forums, and nothing has worked.

I've tried:

1. Using the latest version of VMware Convertor Standalone.
2. Using version 5.0.1 build 875114.
3. Accessing the source files on the local stand-along workstation.
4. Accessing the source files on the remote server.
5. Loading all versions of the standalone on the server (while booted into Windows Server 2008 R2).
6. Accessing the remote machine using loopback adapter IP address 127.0.0.1 as the host.
7. Running under just about every privileged user account.

I have about 10 hours into this problem and I don't know what to try next.

I simply cannot load ANY VMware Workstation VMs into the conversion tool.

Any thoughts?
