I'm having my own issues now. rF2 simply has stopped working. Back to the old UI, it will lock up and not allow any buttons to be clicked, except for a split second every few minutes. I returned to the new UI and that works smoothly, but it stops at about 96 or 98 percent of track loading. I've let it sit there for over 15 minutes on two different occasions. EDIT: Solved. For some reason my audio driver settings changed and no applications were able to play sound. rF2 thus was hanging as it tried to activate the sound driver.
