Vista Ultimate Errors

I have a D-Link Rangebooster G Desktop Adapter and it used to work out just fine. Last week, it stopped working and I had a couple of errors while reinstalling the driver (see error 1 and 3 images). Today, I installed the update for the drive from the D-Link Website and for some reason it started working again. But now I have new errors. Error 2 image pops up when my system starts up. I am also have ethernet controller problem...i am assuming my ethernet plug does not work. Please help.
