I can't import or see video after install 6.0.3

Hi. I’m PC guy. After install 6.0.3 I can’t see video imported on my previous project (6.0.2). Besides, I tried to import the same videos that before I saw, and Import Video dialog box says “Invalid…”
Also, I tried to import formats avi, mp4, mpg but I couldn’t import any file.
Someone can help?
Thanks in advance,

Have also had issues with video import. In my case the audio arrived at a different length to the image. Only sensible answer so for is roll back to .02 and pray for a thorough update. :angry:
