My Majestic Vented Fireplace won't ignite?

I have a Majestic fireplace, recently I flipped the wall switch to find that the fireplace would not ignite. Upon further investigation I saw that the pilot light was no longer lit. I re-lit the pilot and flipped the wall switch, it took a while but it eventually ignited. Several hours after I turned the fireplace off I noticed that again the pilot light was out. I just re-ignited it and flipped the wall switch. The main burner will not ignite. I even went so far as to remove the "logs" and use a lighter to ignite the main burner. No luck... Can someone point me in the right direction? Thanks!
