ArchiCad 21, Teamwork and Windows 7

[Anonymous]

I run ArchiCad from two computers. One with Windows 7 and one with Windows 10.
On both machines ArchiCad runs fine. I have worked on solo projects on both with out issues.
The problem is that on the Windows 7 machine when I try to connect to a Teamwork project, ArchiCad freezes during the "Get Content 4| Post - Processing". The same teamwork project loads without issues on the Windows 10 machine.

Any ideas of how to fix this?

P.S. I know AC21 was not tested on Win 7
