You must make sure to remove all drivers that are on the computer for your device left after plugging it in, and use Wugs and follow the driver installation instructions he even provides the program to remove the old ones and the correct drivers, and after following his tut you should have the drivers installed correctly and when you've done it you can even test it to make sure they are installed right. I'm not being funny but if you can't get the drivers installed I would avoid the whole process as you need to know what your doing and if you do brick it you will struggle following the tuts like SDK to get it back. Think about it.
