Same here. When I select the No Reprieve, Fait Accompli or LZ Nowhere campaigns, the only button I get at the bottom is Continue. This continues the original campaign ("Situation normal").
If I double click on No Reprieve, Fait Accompli or LZ Nowhere it also continues the original campaign ("Situation normal").
I verified game files in Steam and have reverted my original campaign back to the start. Can't play Tac-ops at present.
