You could make a cdp of the 2 assets, save then delete from cm. Close trainz down, wait a minute or 2 then restart. If the find objects problem persists re install the cdp's, if it's ok at least you'll know what caused it.
I have neither of those 2 assets in 2010 but this doesn't mean they are at fault.
Well, I looked up and learned how to save a CDP File and Delete an asset in CM, and I did it . then turned off computer and started TRS10 up again but still can't use find object.
I wonder if I should consider trying to un-install and re-installing TRS10 ?
I'm just not sure how to do it without loosing all of my assets that I have collected.
