OK, I finally found time to figure out how to try both of those things, and now the game locks up on a new, low-res, settings readjustment before character selection. I'm not particularly computer savvy. Any other suggestions?
I'm having the 'Tradecraft' issue as well as a another Rom past that mission where the next won't let me start (I think it's the Nimbus III mission, important to Roms...) A new TOS track has an item that wont interact as well. 3 spots stuck.
