I encountered my first problem at the rope slide.
Downloaded latest re release of no cd fix from gamecopyworld and finally got passed that then -
I encountered my second problem at the wall climb.
In both cases it was after a autosave, in both cases the cutscene shows you companions starting to do something, freeze there, then disappear and end up at the finish of what they were doing, but you cant do anything. On the wall climb, the cutscene shows them jump up to a ledge, they hang there for about 3 seconds, dissapear and show up on the top of the left building near the ladder.
When I jump up to the ledge, I cant pull myself up by using the space bar, I just hang there.
