.wmv's getting cut in half horizontally inside Premiere Pro, AE, Media Encoder...

Question

Hello everyone! I'm having an issue using .WMV's within Premiere Pro, AE, and the Media Encoder. Whenever I open the image in a sequence or the source window, the image is cut in half horizontally (see pic below). I brought in an MP4 and had no issues so at the moment I think I have narrowed down to strictly a .WMV problem. The file plays perfectly fine in realtime; audio sounds great, picture (of what I can see) looks good; I am just missing the top half of any WMV file hehe. I have tried the WMV inside AE as well but have the same issue. I also tried to export the WMV with Media Encoder but it exports the WMV cut in half no matter what format I tell it to conver the file to..
My Premiere Pro, AE, and Media Encoder are fully up to date; my Nvidia 660 Ti is up to date; I just installed latest Windows 7 codec package; Just installed newest Windows 7 x64 updates.
Also, this is a big one to note...This is the first time I have used Premiere Pro/AE/Media Encoder on this system. I just built this PC about 1 month ago and have had 0 problems with it across other programs (Photoshop, 3ds max, etc..) I just recently installed Premiere, AE, Media Encoder on it and am running into this problem upon my first bootup of Premiere/AE/Media Encoder.
My system specs are posted below the picture and file specs.
The pic below shows my setup and the issue I am having. The video of Finding Nemo on the left is the .MP4 (specs on file are below) and the video on the right is the .WMV in question (specs also below.)
I have tried multiple WMV's of different bit rates, etc, and all of them do this "cut in half thing.." No issues with other file types though!

It appears that Microsoft has issued the fixed update:
