Hi at the Start of assault on dark athena I have trouble with just walking forward with the W key. He starts walking and then he just stop to the point were I have to keep tapping the W key. Anyone else have this problem?

It's gone away for now I uninstalled it and removed all save files and cache files from my PC and then downloaded the latest installer. That seems to have fixed it. Try it your self and if it works I'll mark it off as solved.

Not needed, the walking problem mysteriously solved itself.

Well that's just weird.

Maybe it was not entirely mysterious after all, I have been trying out some old keyboards lately, so maybe that has something to do with it.

Maybe but it still shouldn't happen.

perhaps you've already solved this problem, but if you need more help then you can try this.
if you have an xbox360 controller attached then unplug it before starting the game

I have found a Solution to the immovable Key Issue! (Well, for me)

When I unplugged my controller, the W and the D keys functioned as normal!
Hopefully, that will be a simple and easy thing to try before you do anything drastic.

Forward key is also not working from the very beginning in The Chronicles Of Riddick Escape From Butcher Bay. I have a Dell Inspiron 5000 Series with Radeon 530 Laptop.
