Hi,

If you did not change any thing then it is strange. Please check as follows:

Open Magix Music Maker

File/Load arrangements

you will see file name on left and on right arrangements click on it and

to All files now if there are any back up files which generate automatically

in case of problem by magix with extension BAK you can see example

your mmm file

techno trance.mmm

your bak file of same project

techno trance.bak (choose your back file)

it will open all you saving as it is.

In casse there are no bak file then, if you are sure you did not delete anything sinc eyou are facing this problem then clear browser history, cookies, trash bin. Turn off your computer and restart then open Magix and try.

If you still facing problem the best way is to re-install Magix Music Maker if you can.

Note: back up all your projects, all your beat box or any other presets. You can copy them back after reinstalling.

Thank you
