Like from title, I had to reinstall HM2 and now the HUD does'nt work anymore on zoom tables.
I tried all the steps in your troubleshoot guide and deactivated microsoft security essentials and the firewall (that did'nt give any problem before anyway).
I tried to reinstall the last update and the whole HM2 a couple of times, I'm sure it's been importing hands (caddyreport also works in real time) but the hud stays in 'waiting for hands' .
Also reinstalled .net framework and so on.
In the user/appdata/temp folder there's no starscommunicator file, and it does'nt get re-created even without antivirus and firewall (not sure if that helps, was reading past forum posts with my same problem).
