Have you gone back to the Jedi Enclave and seen that it's all fixed up? It should have said at some point in your game that you need to go back there to see the Jedi Masters or something. If you go there and it's still in ruins, then you've missed something. (Have you met/talked to/killed all the Jedi? Seeing as you're Sith Lord (nice!), you should have killed them all.
So try going to Dantooine and go to the Enclave. If you do though, make sure Kreia is in your party, or the game will glitch, causing it to freeze. (or at least, thats what it did to me every time until I stuck her in my party).
Equality is a perversion of the natural order!…It binds the strong to the weak. They [the weak] become anchors that drag the exceptional down to mediocrity. Individuals destined and deserving of greatness have it denied them. They [the strong] suffer for the sake of keeping them even with their inferiors.” - Darth Bane
