Mass Effect 1: remapping keys issue

[liAmarine]

Hello  there,

I've recently decided to star a new ME trilogy playthrough and launched ME1 for the first time in many months. I always remap all my keys because I don't use conventional WASD movement keys (Yeah I'm THAT gamer who plays with arrows). I built a new PC a few months back and thus all my custom settings were gone so I had to redo everything.

Here's the thing: I'm trying to map my skill quick slots to the numpad. I've never had any issue with doing that in ME1 before; but now I can't do that apparently. I get an "invalid quick slot key" error message. I don't get why I cannot bind the numpad keys to skills now, when I can map them to other things like grenades or whatever. Is there any reason why that doesn't work now? I'm quite bothered by it since I can't use any quick slots and have to bring up the skill paused menu everytime. The DEL, End, Page up, etc pad is also "invalid" and I don't have any other keys around my main hand that would help me with quick slots.

Thanks for any answer!
