The Blueprint Editor is not reading (converting) the igs file correctly. When I create a Blueprint for a simple scenery object:

and then select export; the texture and geometry files are created and exported but the bin file is not created and exported and the editor renames the igs file in the Blueprint and throws up this error message:

I have re-verified the game cache and the problem still exists. I have written emails to RS to make them aware of the problem, but the more of us that email them with the complaint, the more likely it is that they will do something about it.
If someone is not having a problem after the update, I would like to hear about it. If you are having the problem, please send an email to support@railsimulator.com. (also please take the time to reply to their automated reply and restate the problem)

I, too, am having problems, but of a different nature. When I enter the scenario editor, I cannot see any track marker posts. When I attempt to add a siding marker, I see two yellow posts but no red center post and the marker does not save. When I go to the 2d map in the editor, I cannot operate any of the switches. This all happens no matter which scenario I choose to edit. When I went to Steam and verified RailWorks2, I was notified that “31 files failed to validate and will be reacquired”. After this finished, the above problems were still present. Can anyone tell me if my problem is part of this topic's subject? Many thanks.
