Lexmark X2480 - Driver installing problem

[Timonen]

I have Lexmark X2480 All-In-One and for some weird reason I can't make it work on my Windows Vista Home Premium 32bit.

I didn't have the CD because I bought this from a friend who didn't have it anymore. I downloaded the drivers from Lexmark's web site (and yes, I selected real version of windows and all), installed it and when I try to use it, it just says following:

• Lexmark All-In-One Center
  The Lexmark 2400 Series printer driver is not installed.
  Please reinstall your printer driver.

I reinstalled it, but still it does that.
Any suggestions? I would really love to get that thing to work.

...Anyone?
