HITS healed itself.
When I first saw this thread I decided to try duplicating it for myself. Duplicated! HITS was not working. All I got was a magenta single line route, with no rails or other components even though they were all enabled. This is on Win7 PC iFly 10.3.55 which had run simulations numerous times and HITS always worked previously.
Last night I decided to power down the PC and do a cold reboot in the morning and repeat the experiment. Before power down I noted that Windows had updates waiting, so I accepted 1 required and 9 optional updates. Then proceeded to shut down.
This morning I fired up the PC and did a few simulations. HITS working again.
I suspect it was an auto-update to Win7 that caused the issue and the later one that I did, repaired whatever that flaw was.

PS: My other Win7 PC is running 11.0.2 and a) did not lose HITS functionality, and b) did not offer an update last night. However, I just rebooted it as well, this morning and it just now popped a Windows message "You must restart your computer to apply these changes". So I guess it is doing auto updates.
