Hi to all!A few months ago I started messing around with the SDK and I remember having to edit a few things in my FS directory, but don't ask me what they were.Recently I started using my PMDG MD-11 once more, but for some reason the Add-on tab doesn't contain a PMDG option anymore. The Level D and FSCopilot and all of those are still there. I have tried re-installing the PMDG MD-11, still no joy.How does one fix this, as I'm not keen on re-installing FSX...Thanks!
