Premiere Pro 15.4 Will not Load Projects on Windows

[Ian Lococo]

I am unable to open any project files in Premiere Pro 15.4. The loading bar freezes around 75% every time. I have tried all of the standard troubleshooting tips and nothing is working. However, I am able to open the project files as normal on a Mac with the same version of Premiere Pro. This issue isn't just on one computer, it is happening on every Windows computer I have with Premiere Pro 15.4 installed on it. I want to know if anyone else is having this same issue and if so what is the fix or when will the program be patched. I would appreciate your help.

• Launch Pr from a shortcut (desktop, start menu, etc.)
• When the main program window appears, and before you try to open *any* projects, go to Preferences>Media Cache and delete *all* your media cache files. 
• Close Pr. Reboot computer.
• Launch Pr from a shortcut again and choose a project to open. Hopefully it will open as expected.

I figured out the problem. The project file will not load if the computer is connected to the internet. I'm not sure what would cause this, but disconnecting from the internet seems to be a temporary fix.

Interesting.

If you successfully launch the project when not connected to the Internet, if you subsequently close the project, connect to the Internet, then re-open the project, does it work as expected?

[Ian Lococo]

It works as you said, but you have to reconnect the media before you can close and re-eopen the project again with the internet connected. For some reason Premiere did not want to open a project with offline media. Once all of the media is online the project file opens normally.

Not a general thing for Adobe to fix. Jeff is showing the correct way to troubleshoot this on your computer. And yea, something like this is a royal pain.
