In TRS2006 I Run:
TRS2006/Bin/Launcher.exe
and
TRS2006/Bin/CMP.exe
Properties, ticked off "Run as adminstrator"
I also have made Antivirus "Alowable Exception Rules" "ALLOW"
TRS2006/Bin/Launcher.exe
TRS2006/Bin/CMP.exe
I turned off my antivirus (temporarily) when installing Trainz
Perhaps 09/10/12 is similar ? ? ?
Also the Planet Auran-Edit Profile and Edit "Password" (it can be the same PW) sometimes resets or refreshes, your account.
As does blanking out your Trainz "Options" UN & PW ... saving as blank, and shutting down Trainz for 15 min, to a day ... and eventually re-entering the UN & PW and saving.
EDIT: I did read that you are running 09 ... possibly some of the applications and fix's used in 06, work for gettig 09 running also ? ? ?
