Sorry, some offtopic remarks needed to go, please stick to the issue.
As far as I know ZA only support English, Spanish, French, German and Italian. You have to install the correponding version based on the system used.There are no localised version of ZA 10 yet, not ETA.
If you have been using ZA before on a non-supported language and it worked then you have been lucky. But as far as I aware these are the languages supported. Also the error may not linked to your OS.
You could use the old version 9 up to expiring and the try your luck again with a different ZA10 build or choose a software that works on your system language.
P.S. changed the title of the thread to point to the likely issue here.
