Cursor not working

[Demonseed]

I've read other people having problems with this (in internet search). I went several pages deep, but couldn't find any other threads about it here. I installed the game. The first few times I tried playing it, my cursur got stuck in the top left corner. Then one time it decided to work and I started to go through the set up of the game. Then an update showed at the bottom right of my computer, which caused the screen to go back to the desktop and the cursor got stuck again. This is the first computer game I have tried to play (beyond solitaire, etc.) and, unfortunetly, I barely know what I am doing. I don't understand the troubleshoots as it seemed like I might have to download something and I'm leery about that. For more info, I am using a laptop, a hp Pavilion dv4-2145dx Entertainment Notebook. Any help is appreciated.
