Follow the link for the SP1.
To install the service pack you need to:
1) Backup any personal content - routes, sessions you modified, or anything else you want to keep. Do a backup of your current install.
2) Turn off Antivirus program
3) Disconnect from internet.
4) Uninstall TRS2006.
5) Reinstall TRS2006.
DO NOT RUN TRS2006. DO NOT EVEN START THE LAUNCHER
5) Put in SP1
Let it run. Plan on doing this overnight. When the patch completes. It may ask (can't remember) to run a database repair, so.
6) Follow any on-screen prompts.
7) Open Content Manager
8) View faulty content.
9) Highlight (select all) faulty items.
10) View errors and warnings to clear up any false errors; anything left needs to be repaired in order to appear in-game.
Hope this helps. It's been awhile since I've installed TRS2006 so my details maybe a bit sketchy. Others can help, perhaps since the product is quite a bit dated now.
