Most likely, you have too many lights. What you should do, is as JeeJee said, release a Beta 1 without the lighting. There's a bit more than 15 hours left in the contest (look at the time in Midway, as soon as it turns to the 30th, no more entries will be accepted). You can try to fix the lighting during that time, but if you can't, you still have the lightless version available for participation in the contest.
