Arduino Nano HElp

Hello guys, recently got a Arduino nano from eBay, however, when i plug it into my computer, and try to update driver, it cannot detect it and says "windows has determined the driver software is up to date.." but it still is an unknown device. any idea what is wrong? i am using Arduino 1.04. And just an additional info, i did try to manually update the driver. Thanks a bunch!

(1) What os are you using? (2) By manually updating drivers do you mean you went into device manager and told it where to look or did you install them straight from the drivers directory? (3) Is the unknown device under COMS?

Hello, i am using Win, yes i went into dev manager. i managed to solve it already, i just had to use the FTDI folder under driver =) thanks!
