Creative Cloud or Premiere pro locked my files

[WoodenWave]

After a lot of tries i got Creative Cloud downloaded again and installed premiere pro to do some video editting, however after i did a new problem arose. All the mp4 files i try to open comes with an error message.

Yesterday i had no problem with my files but creative cloud or Premiere pro made this happen. 

Anyone know how to fix this (I tried youtube but its just alot of dodgy vids that have bad reviews)

Hi @WoodenWave,

Thanks for the message. Can you try reinstalling Premiere Pro? That may help. Let us know.

Thanks,

Kevin

Hi Kevin

Thank you for responding.

I tried uninstalling Premiere Pro but sadly it did not help.

This is making me think creative cloud itself somehow either locked or made this problem, because i can import and use videos from my files in premiere but if i try to open them myself on my pc that same message comes up. 

Creative Cloud might be preventing me from seeing mp4 & mp3 files i previously had no problem with at all. 
this is very weird
