More Issues with my Game

Well since my other thread was closed, I'll do my best not to get this one shut down.

I have run into several other annoying issues, my game is completly out of box unpatched, and refuses to be patched, the patches when downloaded don't register that I even have the game installed, and now I can't even play it, its crashed when ever I open the logbook-clipboard, or try to fast foward time, or go on to the bridge, or really do anything other then studder (its lagging bad) in the command center. What did i do wrong? It worked fine untill i had to err.. do stuff that got my last post locked after my disc got broken. I'm not buying a new copy, I cant afforde to. I just graduated HS and have noo money. I spent the last I had on SH.

Someone, anyone, help?
