Hey Dave, I did get the following help from the Trainz person a few weeks back that helps with PURCHASED items from Sim Central
Good Afternoon dft7295
For your issues with the Download Station, are you downloading using Content Manager? Or have you downloaded a 'cdp' file from the Download Station website?
In regards to the DLC packs, the installers may not pick up on the Steam editions of Trainz. However, please ensure that you are pointing the installer (using the 'browse' tool) to the actual Trainz folder in Steam. To do this, please first locate the Steam folder, then open the folder called Steamapps, then open the folder called 'common'. You should then see a folder marked 'TS2012', please select this as the install location.
We are currently developing the Service Pack 1 update for the Steam editions of Trainz, which will improve the handling of DLC packs. We do not have an ETA on the release of this, however it will be after we have released the hotfix for the 'base' TS12 editions SP1.
Regards
Zec Murphy
(I hope they don't mind I re used it)
And Shane, no error message, I sometimes get something like "checking for missing assest database" and once it loads, nothing. as usual. But normally NOTHING at all happens.
