I started installing the latest update (1.1.0.73) and got an error message from MCC. I tried again and it worked but I was very upset for a few moments thinking I may have lost the Matrixbrute by installing new firmware.
Matthias posted this video which displays the same problem that I had. Wish I had seen this before I tried my update I would have expected the glitch.
here is video
