I recently got a virus and had my computer wiped and reinstalled Windows XP Pro. Now my touchscreen and function keys don't work. I tried downloading drivers from Panasonic's website, but after unzipped when I try to click on any of them to install, nothing happens. I have 2 part numbers on the bottom of my laptop, CF-29ETPGXKM and CF-VZSU29 and I think the first one is the number I need to be looking at but on the website it only shows CF-29ET and the rest of the letters are different than mine. Am I downloading the wrong drivers or am I doing something wrong in installing them?
