.cache\<id>.bik File Not Found Error When Attempting to Load .mp4 file

[GetOutOfSync]

When I was attempting to replace the bootup cinematic with an .mp4 file, I ran into an issue where several .bik files were unable to be found under the .cache directory, preventing the system from loading the file and prepping it for conversion.

The following is an example of the error I am getting in the console. There are many files that I am slowing creating dummy files for to try and bypass the issue, so I don't know how many are missing as of right now. Working on getting a full list shortly.

Exception in Tkinter callback

FileNotFoundError: [WinError 2] The system cannot find the file specified: 'C:\\<Install_Path_Here>\\.cache\\1772757879551.bik'

I am using the Windows executable, version 1.19.3. RAD is installed, and is able to view pre-existing video files within Audio Modder just fine. I also installed version 1.19.2 and checked the .cache file there, but it was also empty and would cause similar problems (I assume anyways).
