I am sure that this topic has been approached in previous threads, in fact, I just looked through "raildriver problem," just to be sure that this was the correct forum. I just received my Raildriver from Schrader Enterprises, and am having problems. Following the instructions on how to install R/D on MSTS, I am secure in the knowledge that I have completed those tasks satisfactorily. My problem lies in the actual operation. When I select "Dash 9" on Raildriver, and select "play," MSTS loads (takes a couple of minutes), and then select a route (in this case, 3DTS's Cajon Pass-High Desert route). I select a scenario (BNSF Barstow to Mojave, which features a Dash 9 locomotive), I click "start" on the MSTS game with my mouse, and then MSTS starts its program of checking terrain buffers, world situation, etc. Just when the selected scenario gets near the completion of its loading cycle, I get a brief cabview of my locomotive and the tracks ahead before the screen goes blank. This is not the dreaded BSOD, but just a blank screen with "Train Simulator" in the upper left. I end up having to CNTRL, ALT, DEL - and then telling my Windows manager to END the program. Next comes up the option to report a problem to Microsoft, which I decline. I've read in the tech manuals from PI Engineering that I may have to disable something in my graphics card??? Geeez, I thought technology was supposed to be "plug 'n play," or "simple." MSTS operates just fine without R/D, so if suggestions or links are offered (so please don't take this wrong) and they are not understood by my non-computer brain, I will wrap up this Raildriver, and return it for a refund. Thank you for any assistance you can provide.
