Got back to the starting house. Found the jumper cables and the helium tank. In the front courtyard, your supposed to attach the jump cables to the car battery and what?

I might have the same problem. I am actually pretty sure I know what I am supposed to hook the jumper cables to (Pascal even told me) but there is no hot spot to do it. If there is a hot spot on that screen I have not been able find it, and I have looked and looked...
Seems strange that I can't find any other mention about a jumper cable bug anywhere. there is no difference running the base version or the first patched version

That is what gets me really annoyed. Was there no ( alpha or beta ) testing for this game?

Good to here someone else has hit this wall as well.

Don't get upset! Those cables are supposed to be plugged to the car's battery, but you need to do something else before that. Let's say: there are some guards nearby, that are going to have a shocking experience...

I did finally figure out, as wehkah pointed out, that something needed to be done before the jumper cables could be used
