Try adding the language settings of Windows to English, or if you already have more than one language pack installed, then switch the language to English.
The menus etc should then switch to English.
If this fails then contact Sales at Magix, you may have to buy the English version
Johnebaker, it won't help because of different approach. I contacted to MAGIX and they have told me, that they produce only Spanish, Italian, Deutch, Niderland versions. For original English language in the program I shoud use XARA's version. So I uninstalled Spanish one and installed the one from XARA. All works!
