MPC Keys Since The Update 2.11.8 It says no more Favorites

Hi,
Since The Update 2.11.8 i have an Error that says The Favorites Presets And the User Voices does not exist anymore !!!!!!!
What does it mean ?
I made so many beautiful Pianos Etc.... for Nothing ???
Why do Akai dont whrit it somewhere, that we know that they change everything ??
So i am going to stay on the Version 2.11.7 there it works fine...
But in the Future i am not going to buy anithing at all from Them.

Akai Its a Synthesizer and on a Synthesizer we need the possiblity to save changes on Voices

This was a known bug a while back. Update to the latest OS.

Thats what i did Yesterday ... same Thing ?????

Hi,
i have to apologise ....
i mad an Update to 2.11.10 and Everithing works great...
could not try it Yesterday, the Download did not work directly from the MPC Key 61.... it says error downloding.
Today i started my MPC Keys 61 and it says there is an Update do you want to run it, and thats what i did ...
Great , very happy
Thanks Delphinus
