Upgrading DirectX did it, thanks! Didn't know there was another one out, haven't gotten any games new enough to need it...

I've just had time to flip through the menus and tac displays, but this looks so much better now!

Does anyone know if this is even the error associated with an incompatible graphics card?

<t> Just got the full version of the game (about time I bought it, been following on and off for about 4 years...), and immediately patched up to 4.5.0. But when I try to run it, I get an error, something along the lines of "cannot allocate enough memory". I do not get this error when running 4.0.3 ...
