Weird. Can you  email [installation directory]\32bit\logs\proseries.txt to proseries_engineering@intuit.com?

I'm hoping it has more detail as to what is going on. 

Also, can you confirm.. are you transferring via File->Transfer?  I'm not sure what you meant by "it pulls up all the clients last names and part of their social".. but i'm also not as familiar with the Network product.
