Garbled green & red screen when using 1.4b patch ?

[Paul Riley]

I am almost ready to launch my first career after a while away from the game,and I just got the 1.4b patch from filefront.I launched the game but appear to have got a garbled green and red screen with blocky graphics on the intro screen (with the ship movie).I havent updated to GWX3 just yet,I wanted to fire the initial stock game up then proceed to apply all the neccessary mods etc I have waiting after I got the stock game up and running.
I am unsure as to whether this is linked to my graphics drivers (doubt it as all other games are fine) or I have a bad copy of the patch.
I suspect the patch is bad,so could someone provide me with a good link to the correct patch? (UK,DVD version)

*I seem to recall seeing this a LONG time ago with the stock game,is this a recognized bug?*

Thanks.
