Everything was playing fine last night, but today I’m getting errors about the codecs. I noticed this site said you thought you had fixed an issue but to open a forum topic if we’re having issues. Please advise on how to fix this asap

I chose to exit PMS from the system tray of my PC and then relaunched it after I saw that it was no longer present in task manager. If I was off base in my approach or understanding then please let me know what I should do.
