"Sorry, The file could not be found" when trying to view clips/alerts

I encountered a similar issue after upgrading to 5.0.8.2.
It went away after upgrading to 5.0.9.0, rebooting the computer and rebuilding the database. Not all of those may be needed but it is what I did.
All of the recordings from the time I upgraded to 5.0.8.2 until the update to 5.0.9.0 are unreadable.
 
They are readable in my case, but requires either a repair database (rare) or in most cases a reboot of the WD MyCloud. As soon as it reboots, BlueIris again can access the files as usual. Within 2 days average, same process again. Continuous record and alerts all continue to save to the MyCloud, just can not find the files when attempting to view.
 
Got it, I cannot access any of those recording made during that period.
My recordings that were affected were being made to 4TB internal 3.5 drive connected via SATA.
