bump, any help?

Am I doing it right? I'm a Jedi Knight Sentinel, trained Artifice, Archaeology, and Treasure Hunting. My Arch and Treasure Hunting are 100+ right now. But for 3 straight days, my artifice skill hasn't been working... Am I missing something here? Is it a bug? or do i have to be at a certain place to craft using artifice? I have the materials and all of that, and all three of my companions seems to can't craft artifice stuff... help? o.O? THanks =-D
