Sadly, my Windows 7 workstation died and I am reluctantly having to move to a Windows 10 installation. TMG 9.05 appeared to install fine. I then ran it in administrator mode and entered the registration details - which were accepted. So far so good.
The situation now is that when I open TMG normally, it tells me I have an expired trial version - but if I open it in administrator mode (lots of extra scrolling and button presses) it opens with the full registered version.
Is there any way to have TMG open normally into the full registered version? (I'm presuming I may have missed something obvious!).
