Error message/ workaround for OVF Tool?

I downloaded all the files (vmx, both vmdk's etc) from an ESX 3.5 host to my local UNIX box.

Then I ran the 0.9 version of OVF Tool (release 62566) and get these errors:

Opening VMX file: MyMachine.vmx
Analyzing virtual hardware
Opening MyMachine.vmdk

Can anyone tell me what is wrong here?

I'm using OVF Tool 0.9 because I need to generate a version 0.9 OVF file for this VM....I can't figure out any way to preserve the 0.9 versioning that I need for legacy support purposes.

Thanks for pointers,

CJ
