I've downloaded STK 1.0.0 and found that it totally doesn't work. Every time when it's needed to choose a kart, it becames Not Responding. When I open single-player mode, list of installed karts is visible, but STK is Not Responding. When I open multi-player (not networked), list of installed kart is visible, but STK becames Not Responding when I press 'fire' to choose a kart. When I open Tutorial, STK becames Not Responding. Same for when I open Story Mode, but there I can see only black screen with fps in the corner.
I can't play game, only viewing servers, changing settings, and installing Add-Ons.
STK 0.10-beta had worked perfectly before I've installed 1.0.0, but now it behaves in the same way. I haven't installed 0.10-rc1. stdout.log files contain no intresting info (I can attach it if you say it's needed, though).
