Hi. I too have been having problems with the GP7 repaint. As mentioned before, the SAL model works fine and I've downloaded it from both sites. All of the other repaints load correctly and work beautifully. (Thank you very much for those BTW). I have followed the instructions to the letter each time. I have installed, deleted, reinstalled numerous times but get the same error at the same point. When I click on the engine in the list all is fine, but as soon as I attempt placing the unit on the track I'll get the error message stating: "Something bad happened..." and it generates a dump file and RW shuts down.
Hopefully someone will think of something. Meanwhile I am enjoying Michael's other engines on the P&LE. Thanks again Michael. :)
