"The activation of AAC (MC) failed" when importing media

I tried everything:

1. Resetting Vegas Pro

2. Reinstalling Vegas Pro

3. Deactivating Vegas and then Activating it again

4. Run as Administrator

 

None of the above worked.

 

I bought Vegas Pro today, and the activation with the serial number worked fine, but when I try to import any of my MP4s or even a Vegas Capture project, I get this error.

Note that I could download a video from the Hub and use it just fine...

Help!

Since I work with MP4's created in my Panasonic cameras, I've always been able to bring them into Vegas.

Would it be possible to send a test file that doesn't work to the cloud to download and try?

Nothing is working. I even tried Vegas Capture (which works fine) but I cant import the project files of Vegas Capture; I get the same error

Seems like the same issue as here. Do any of these solutions help?

If the media doesn't have AAC audio this error wouldn't appear.
