SBS v7.6 server.log

I'm having the same issue with SBS v7.6 as with v7.5. When I enter my username
and password for mysqueezebox.com in pref pane, I get: "Invalid
mysqueezebox.com username or password." This issue does not exist with my
32-bit Macs but exists with my 64-bit Macs. Please note that both v7.5 and v7.6
SBS work properly in all other respects. 

The new version 7.6 also interestingly runs in 32-bit mode, like v7.5, so most
likely there is some breakdown in both 7.5 and 7.6 when the preferences pane in
Mac has to re-start in 32-bit mode to access SBS. Is there a fix for making SBS
run properly on 64-bit Macs? 

Both scanner and server logs are attached for my 64-bit MacMini where the
problem exists.
