Personal lifetime license

My Midi guitar 3 does not work on Cubase (Windows). I have tried everything and does not recognise the Midi from Midi guitar 3. I purchased it for windows and I do not feel like paying again to use it on Mac system. So much many already. I have swapped to Mac and it works, but I need the license for Mac. Is it possible to get the license for mac here?

Thank you.

There are quite a few here who use Cubase. According to your email you need to get the buffersize into a usable range with your audio interface / ASIO driver.

You don’t need to buy another license. I’ll get back to you on email.
