well, to save it, do this to every letter:
1. Go to your auran directory file, into the trs2006 folder, and remove the local folder right out of the trsfolder.
2. Then go through, and delete everything in the TRS folder. (place the Local folder on your desktop)
3. then, insert your 06 disks and uninstall TRS.
4. once thats done, reinstall TRS, BUT
DO NOT run it.
5. Install Service Pack 1, then go back to your TRS Directory folder. find the new local folder the disks put onto your computer, and delete that, but dont remove everything from the TRS folder.
6. Place your old Local folder into the TRS directory folder, then close out the directory. Open it back up, and look for a file called 'assets.tdx' delete this.
7. Then run Content Manager Plus, and the game should read all the content you had on your previous local folder. Routes, Locomotives, everything saved.
Glad to help
