I recently downloaded 2 Amtrak locomotives for TRS2006. I installed them using CMP(or at least it says that it installed them. When I start TRS2006 I get this message: Some of your content has not been commited, would you like to start Trainz anyways? If I do start TRS2006 then after the message neither locomotive is there. Could someone please help me with this problem? Thanks ahead of time.
