I can't help you any, BUT a LOT of the "techy" guys are at the meet n greet, so I'm sure one of them or some of the other guys will be readin' your post and help you out.
I haven't used my furnace in quite a while (I cheat with electric heater) so I don't really remember if there was any "clicking" just prior to it igniting. Also, right now with the temps pretty warm you will probably have to have your thermostat set up to about 90 in hopes of it turning on. But, I didn't notice where you are located either.
Don't give up, the guys will help you get it going.
