The last time I was playing TW1 was about a few years ago. I wanted to install and play it again...

First I had these problems with .dll and system requirements, but I've solved it. When I thought that it will run normally from now... I was mistaken.

I can't make any decision, even in casual talks (first one with Triss about Geralt's memory loss). My Geralt automatially chooses his lines. The window at the bottom where I could choose an dialogue option doesn't appear at all. I've stopped playing when I couldn't even decide if I wanted to go to the labs (I'm talking about the prologue) or fight the monster (I don't know its name in English). He chooses to go to the labs. :P

I didn't find anyone with this problem anywhere at the Internet. I've reinstalled it many times and it is still the same. Also, everyting works fine on my brother's computer. And the tech support doesn't respond for a week. .-.

Help? Pleeease?
