I can't access the workbench no matter how many times I try, and I've tried different ones throughout the game. I can access lab stations just fine. What is going on? The only way I can upgrade items is with T3. Has anyone else had this problem? Is there a solution?

you running from the hdd or backup dvdr or reatail disc??

I've tried both.

you might have to delete your save and try again also with or without the disc the game is bugy its the new company obsidian

I Havn't had any trouble running it off the Hard Drive after I past the black screen part

ok I got passed the black screen all I had to do pause it as soon as it was black then I SAVE IN "NEW SLOT" then load it dont replace your old save

Had the same problem as you do.

Put the game on HDD, deleted the cache files in Y: and modified the SwkotorIIdirs.ini to point where the game is on my hdd. Worked pretty good on my xbox and my friend's xbox, although is problem was that he couldn't see the missions.
