Unable To Load File VP 12.05

[Rockyk]

Ok I've been using VP 12.05 64 bit flawlessly since it arrived. I've been working on a project over the last 6 months with zero issues. Out of the blue I started to get "failed to load file" messages when working with existing video assets upon load of my project. I inspected all files, checked names, did my due diligence. Nothing had changed. These were the original files I had used since starting my project. I even attempted changing the file name to see if it was just a glitch. Nothing. No matter what I did I could not load the clip(s). Did a full uninstall and reinstall, problem still there.

I eventually upgraded to 13.67, files loaded, but it won't export. Downgraded to 13.66 same scenario. I'd really like to get back to using 12.05, as I said before it has been a rock solid performer. All subsequent updates seem to lag and not give the results that I've enjoyed this far. Any idea as to the root cause in 12.05?

My current system specs are

CPU - Intel Core - i3-1005G1 @ 1.20GHZ

GPU - Standard Intel UHD Graphics Card

32 Gig - Ram

2tb -SSD

Let's take a look at the project.  Someone will run tests.

The process is easy, quick and can be done privately.  Just follow these steps...

•     Back up --- With your project on the timeline, click on MENU at the top-left.  Click FILE|BACK UP PROJECT FILES TO FOLDER.  Choose a folder and SELECT FOLDER.
•     Upload ---  Use a free server - Google Drive, MS OneDrive, etc.* - to upload the saved, numbered FOLDER.    Do NOT upload the individual VPJ or export file. 
•     Get link --- Get a public link.  If using Google Drive, right-click the file and click SHARE. If necessary change "restricted" to "anyone with the link can view" 
•     Share ---     Click COPY LINK | DONE.  Paste that link here, or click the folder at the top-right of this forum to message it privately to me.  It won't be shared.

          *    Before uploading, right-click the folder, click PROPERTIES.  Look at the File Size to confirm that it's not too big for the free space on the server.

I will send it over later.  Just to be clear though. This issue is happening when I’m trying to load a file from my computer to the media bin. 
That is the part that has me confused the most. With it unable to load. It will remove the clips if already in the time line.  Thank you for your response.

Load it with the later release/s, then Save and upload the project.

I just wanted to circle back on this. I ended up doing a complete uninstall using Revo Uninstaller to remove everything. Installed 13.67. Everything is acting as it should so far. 
Thank you for taking the time to work through this with me.
