Dominik1976: Yes, fresh installation, just bought the game here on gog. no mods/tools installed.
When I'm at race selection, there`s the "stats-tab" on top right of the screen. When you click on this stats button, it shows you the stats of the chosen race (+2 dex, - 2 con, etc). And thats where the subraces should appear too. but there is only the first subrace as an option (eg for elf it's moon elf), all other slots are empty. cant click on them, nothing happens. I bought the boxed version at release and I remember I could chose a subrace back then. Damn, shouldn't have sold it...
Yeah, definitely something weird there then. I just checked my game (freshly installed a couple weeks ago, but not yet played). On Win7 Pro 64 bit. After selecting the race and clicking 'next', I get the subraces. I have the game installed outside Programs and Programs(x86) though. It's actually on a different drive altogether, but if you have it installed in either of those two locations, try installing it outside of there. Something like C:\Games or something similar.
*edit* I also checked the 'stats' screen and everything is blank except the stats for the base race. Just click on 'Next' at the bottom and it should take you to the subrace selection. (I know you said you tried this, but I just want to double check to make sure this is what you did).
