I have a similar problem. I had no trouble with the demo and then picked up the paradox version from Amazon.
I put the correct paradox patch 121 on which cost 1 dollar but when i run a game most of the map appears black until i zoom in.
I tried it on a spare pc and the same happens so I have reinstalled and patched up to 120 which seems to be problem free.
I double checked the email from battlefront and it is the definitely the paradox version as it says CMSF-PX-DW on the email invoice.
Both pc@s use gforce cards which have up to days drivers. one is a 7600 gts about 7 years old and the other is a 9000 series which is about 3 years old.
I fiddled with the GFX setting but got no joy. Im new to the game so im not running it with mods of any kind.
any ideas guys?
thanks
Harv
