Wireless and Ethernet drivers missing

Hello,

I recently uninstalled a game from my IBM Thinkpad T40 and immediatly after uninstalling it, i was unable to access the internet using my wireless or ethernet connections. I then ran a diagnostic on my comp. and found that the drivers for both my ethernet port and my wireless adapter were missing. A friend suggested that they had been uninstalled with the game. I have tried downloading te drivers from the lenovo site from a different PC then transferring them to my laptop with a flash drive but have been un succesful. Any suggestions would be grealtly appreciated.
