RE: [cosmos-dev] Unable to Load the Data Managers

[David Whiteman <David_Whiteman@xxxxxxxxxx>]

I don't know if this is the problem,
Hanu, but another variable I see is that you are using a 1.6 VM.  We
do all our testing with 1.5 VMs.

Anyone else have any thoughts on what
could be causing the error?
