I have used Content Manager for years with no problems until today. I recently upgraded to a new computer operating Windows 7 and I have installed ts12 patching up to build 58414. The installation is on C:\Program Files (x86)\N3V Games. The S&C package installed itself and I have transferred the User Data folder from the old computer. All tested and running correctly except that when I attempt to open assets for editing, Windows Explorer opens in D:\AndrewH\Documents which only has a temp folder in it. When I search the N3V Games\Trainz Simulator 12\UserData\editing folder I find that it is empty.
The install obviously did not go smoothly. I found a corrupted file. To uninstall required a system restore. New installation is running OK.
