The web host that held the ALDL website has shut down. Geoff has moved everything and will be on very soon with the new links. Which drivers did you try to install? What version of Windows?
REMEMBER: You should not have the interface plugged in while you are installing the drivers. For XP, if you plugged in the interface and Windows tried to install drivers, then go into Device Manager and remove the broken driver. It probably will be at the bottom with a big yellow question mark. Just right-click on it and select uninstall. For the newer Windows versions, the process is similar but I don't know the specific steps.

http://www.ftdichip.com/Drivers/VCP.htm and download the executable 2.08.28 WHQL Certified driver.
The executable is
http://www.ftdichip.com/Drivers/CDM/CDM20828_Setup.exe Download this, don't run across the web. For XP, this should be able to run by right clicking it (after downloading it) and selecting "run as". For Windows Vista, Win7 or Win8 you probably should use the run as admin/supervisor option. I don't have Win7 installed anywhere but installing drivers requires admin rights.
