Re: keyboard not working and stuff
DxDiag file like @ThandalNLyman said may help...may..I think you said you are on a laptop?? So I assume you are using the built in Keyboard??
Have you tried a clean boot??This would help cut down on the possibility it is a cross program interference...you can also try creating another profile on your OP system and don't add ANYTHING too it except for Origin and DAI and that would also help eliminate cross program interference.
USUALLY...and as I have said other places, that is a word that will get you in trouble many times....but Usually, this is a cross program interference or a ghost controller/keyboard in the system hardware listing causing issues. So please try a clean boot, maybe even the new profile on your PC and please post a DXdiag file....please.
And sorry I didn't understand about the profileoptions files....I thought you were saying you had deleted the last two saves from your play...
Also does the keyboard not work only on a loaded save, or does it not work anywhere in game?? Otherwise, can you go into options and choose to rebind a key to something new, or does it simply not know a keyboard is connected in game??
