Throws of the races in amerige (Need for Speed: No Limits)

Please help! Trying to race in blackridge, and from there throws me to desktop as soon as I click on the button race... meanwhile, all other tabs are viewed without any freezes or other things... Before that I was playing the opponents of America and everything was normal... All the other races working, playing and tuning the campaign and special events - no problem! In General, come to the rescue! Can someone faced with this? Very sad...
