Marc,
When I run ConBuilder (1.4.9) I get this error:
"The engine file Pro_Series_BUnit.eng contains an invalid name in the line "Wagon". Please edit make sure this line to have (sic) the same name as its file!"
Ran Windows search found I had 2 Pro_Series_BUnit.eng files. One in 3DTrains_FSkin_NYC folder and the other in 3DTrains_FSkin_NYC/options folder. Wagon line of each has BUnitSkin_NYC_2423. Both the "s" and "sd" files have this exact same name and this is the correctly spelled name of those files. Any idea why the error?
