Sony Vegas Mp4 Error

[moezy-chan]

I have used Sony Vegas 8.0c for the past 3 years and started off by using it with Windows Vista. I eventually bought a new computer and upgraded to Windows 7 and it worked fine on both. Less than a week ago I upgraded my laptop to Windows 8 and now it won't read any of my mp4 files. I downloaded the same programs that I did on Vista and 7 and it won't work with 8. I have the latest version of Quicktime as well as the K Lite Codec Mega Pack which I used on my older Windows platforms but it's not working with 8. The audio is registered and works in Vegas but the video won't show at all. If anyone can help me figure out how to make the video show I'd greatly appreciate it.
