I need the Acer Aspire 5315 keyboard driver for windows xp. Anyone can help?

I reinstalled windows xp in my Acer Aspire 5315. I found most of the drivers, except for the keyboard. I contacted Acer support, but they won´t help me because they say my laptop was stolen ( I bought it to someone I considered was a legitimate dealer, but it appears I was wrong). Some of the keys don´t respond as they should, and I´d thank anyone who can send me this keyboard driver, if they have a laptop like mine. You can even download it from your laptop using DriverMax, which is a great program for saving your computer drivers ( I didn´t know of it before reinstalling xp). I´ll thank a lot all the help you can give me.
