Ok guys. It's working now and v2.5 is up and running. Not the easiest program to use as it has 2 settings buttons, only one of which does anything. Also,
the only way I could get it to update to 2.xx was by using the advanced settings tab. I would have thought that updating was one of its basic functions. Still, I figured it out.
Just Judging by the appearance of the planes in v2, it was all worth the trouble! But why do DCS make things so difficult?
