Trouble converting VMWare ESXI to Xenserver 5.5 (Windows 2008 x64 host)

Using many combinations of VMWare Converter and Xenconvert I'm unable to get my Windows 2008 Guest VM on ESXi to move into Xenserver.  On my most recent try using this article: http://support.citrix.com/article/CTX116603

I get the following in my XenConvert log (Xenconvert hangs at 5 progress bars):
