I've been running RA2 fine on Windows XP but when I upgraded to Windows 7 64x I haven't been able to open any arenas on stock or DSL. I've been using the downloads from Sage's sig. When I go into the botlab the game crashes. When I try to enter a tourney I can hear the crowd cheering but the game blackscreens. When I try to do an exhibition match the only arena selection is an unnamed arena. The preview is The Octagon with the heckraisers having a different texture and when I try to play Peanut Botta appears in all four corners then the game freezes. All the arenas are in the folder so what is going wrong?
tl;dr: Can't load any arenas.
