You have tried everything from driverupdating, checking the preferences, cables and other hardware problems (I've tried different MIDI Devices as well as cables for example), different DAW's to reinstalling evertything and so on? But nothing worked and you don't have any clue what to do? Maybe an UNDEFINED EXTERNAL ERROR window showed up? Well then you might be interested in this video here ;)
Sorry for posting this in german since I'am not a native english speaker. If you wish, I could make some subtitles.
You can write in the comments below if your problems are solved, I hope you can make music again without racking your brain about Computer problems. Wish you the best

In case you couldn't find it via the search option, search it on your own!

Du hast alles versucht, und kriegst trotzdem dein MIDI Gerät nicht mehr zum laufen? Vielleicht hat dir Windoof gemeldet dass ein unbekannter externen Fehler entdeckt wurde? Dann wird dir das Video mit großer Wahrscheinlichkeit weiterhelfen und dein Problem lösen ;)
