As much as I can help...
I am using Win 8.1 - so I don't think the problem is there.
I don't know if "1.4.1" actually changed version numbers anywhere that I have seen, so that's probably not a big deal.
When you run attract, there is a separate cmd prompt window shown behind the scenes that outputs some info. Try doing tab -> General -> Window Mode and change it to Window so you can see this.
Also important to troubleshooting:
Are you using the default layout?
What changes did you make to your config files?
Has it already generated your rom list?
Left/Right (the last keys you are pressing) by default change lists, so it may be having trouble re-loading whatever list you are on.. see what the output in the cmd window when that happens.
Hope this helps..
