The session will run even though the engines at Gunnison are derailed. This will be fixed in the next release. I have found that anyone who has SnC installed will have a problem with ths route. It seems that when SnC is installed it changed one or more assets.
Solution steps (method 1):
**NOTE: It is highly recommended to have the database process windows open.**
**NOTE: It is highly recommended to have a First Class Ticket associated and active with your PlanetAuran account.**
**NOTE: These instructions, as with the route and session referenced in this thread, apply only to TS12 SP1.**
1) Launch Trainz. In Main Menu > Options > General Settings, uncheck "Automatically download DLC updates".
2) Exit Trainz. After TADDaemon.exe has exited, go to {trainz-dir}/UserData/ and move the folder "packages" to another location.
3) Open Content Manager and run an extended database repair. Let it run overnight.
4) Set the search filter to "Faulty:True". Wait for TADDaemon to finish validating assets (should say "Assets remaining to validate: 33"), and the "Please wait..." message in Content Manager will be replaced by the list of all faulty assets.
5) Select all the assets, right-click, and choose "Show errors and warnings". Wait for the task to complete. This will clear any false positives.
6) If any assets remain, repeat set 5 for each asset individually, and make note of the errors. If all goes well, you will not have to perform this step.
7) Now bring up the multiplayer session in the CMP main list.
8) Add the filter "Locally Modified:True". If adding this filter makes the list empty, go to step 11.
9) Select everything in the list and press CTRL+O to revert to original.
10) Delete anything that remains.
11) Change the Locally Modified filter to "Installed:False".
12) Select everything in the list, right-click, and choose "Download". Wait for the downloads to complete, then clear the Download Helper queue.
13) Remove the Installed filter.
14) Select everything in the list, right-click, and choose "View Dependencies". If it complains about it taking a really long time, click "Yes".
15) Click "View in Main List" and go to step 8. Repeat until you're cycling through a small number of library assets.
16) Set the search filter to "Out of Date:True" and "Installed:True".
17) Select everything in the list, right-click, and choose "View asset versions." Click "View in Main List".
18) Add the search filters "Obsolete:False" and "Out of Date:False".
19) Select everything in the list, right-click, and choose "Download". Wait for the downloads to complete, then clear the Download Helper queue.
20) Wait for TADDaemon to finish doing its thing, then close Content Manager.
21) If you haven't done so yet, grab something to eat and maybe a few winks of sleep.
22) Launch Trainz and enjoy!
Solution steps (method 2):
1) Install TS12 to a separate directory, i.e. C:\TS12MP. This copy of Trainz will be a "clean" copy, with no local modifications to content - perfectly suitable for multiplayer sessions.
2) Apply the patches in sequence as they apply to your copy of Trainz.
3) Go to the Trainz Launcher and enter your PlanetAuran username and password in the Options dialog.
4) Open Content Manager. If an EDR doesn't start automatically, start one yourself. Let it run overnight.
5) Follow steps 5-7 above.
6) Set the search filter to "Locally Modified:True". The patching process may have screwed things up a bit.
7) Follow steps 9-12 above.
8) Download the route, session, and all their dependencies.
9) Follow steps 16-22 above.
