I have similar firewall problems in that I can see other computers in my WORKGROUP, but can NOT login to them.
I went back to the FREE version and ALL works fine.
BUT I NEED MY PAID VERSION FIXED _TODAY _ NOT NEXT WEEK ! !

OR I need an extension to my expiration date for time LOST, so far about two weeks + until it’s fixed.

Others having firewall issues - TRY the FREE version and ALL works fine.
