Monitors not working - Windows 7

I just recently received my ud-3900 docking station. I plugged everything in and the driver seemed to install just fine. The USB devices seem to work ok, but the two monitors that are plugged into it don’t seem to be working at all. I tried to install the latest driver from the website, but it crashed my computer. When I tried again, I received a message that my driver is up to date. I don’t know how to get it to work.
