AVC/AAC .mp4 60 fps - Premiere Pro CC 2014 doesn't show video

Hello everyone!

I have a BIG problem with the latest version of "Premiere Pro CC 2014 - release 2014.0.1"; i can't work with AVC / AAC video file with extension .mp4 at 60 fps.

When i import the file into my "AVCHD 1080p 60fps" sequence, the video has only 1 "green" frame, and the video file doesn't show properly.

With the previous version of CC, the 7.7.2. version, the same video works perfectly.

How can i fix it?

Thanks
