Sadly, I can't recall having uninstalled anything those days: I only installed Orbx freeware airports (before the issue arose), then Editvoicepack XL (after opening this thread), and then an update to the Fenix A320 for MSFS (yesterday). Hell, I can't even remember having updated Windows! I'm perplexed
Is it there a repair function in PF3? Even with SSDs, PF3 install takes ages
