Error 'consist builder, cant load rail vehicle' etc etc.

[Formidable38]

I have just bought DLC GEML London to Ipswich.
The only 2 scenarios I was really interested in will not load in standard drive.
These are the 2 class 66 scenarios. Im getting the follwing messages.
"consist builder cant load rail vehicle FWA wagon high cube"
and in part 2,
"Consist builder cant load rail vehicle AP Class 321 GA NXEA- (list of coaches).
My questions are, how come it cant find these items as I just downloaded the DLC?
Where and how do get these items?
I messed with the editor in the first class 66 scenario and have made it worse, how do i delete that and get it back to origonal? I thought I re installed the whole GEML DLC but its still there messed up!
I tried clearing cashe but it made no diffrerance.
I could really use some help guys please!

You clearly have bought or added some scenarios from elsewhere. The 'AP Class 321 GA NXEA' is the Armstrong Powerhouse payware class 321 as found here- http://www.armstrongpowerhouse.com/index.php?route=product/product&path=45_84&product_id=137

Obviously not part of a DTG product!

What is the name of the scenarios? I have both and so would be able to confirm for sure whether this is the case.

EDIT: just done a Google search for the 'FWA wagon high cube' and that is ALSO an Armstrong Powerhouse item, its part of their Class 90 Freightliner pack, http://www.armstrongpowerhouse.com/index.php?route=product/product&product_id=148

So that would seem to confirm that you have somehow installed some AP scenarios and dont have the required stock to use them.

If you want to fix any scenarios you have buggered up, follow these steps,

Open your Steam browser and click Library

Select Train Simulator and you will see a list of all your DLC in the middle of the page.

Fine the GEML and untick it.

Close Steam.

Restart Steam and go back to the same list and tick the GEML dlc box.

It should now re-install including the scenarios.

Thanks Simon, Il follow up those suggestions! It all makes sense now.
I had a hunch that it may have been an AP issue as the clue was in the referance to the AP CLass 321 but what threw me was the fact that I'd just downloaded the DT games GEML so expected all scenarios in the list to work off the bat. The 2 Class 66 scenarios that are listed are under the 'standard' tab between carreer and workshop, there are apparently parts 1 and part 2.
Thanks for the reply, much appreciated. Im abit green with this when it dosent work properly.
