In your first post, what does the error message say on the Troubleshooting tab? In your first image, what does the error message box say if you expand the details? Can you translate both of these for me? :)

I've fixed the things in your second post for Beta 11.

I've fixed the missed translation from your third post for Beta 11.

I've also fixed the error in the profiles menu from your fourth post for Beta 11.

I'll fixed the first errors once you can give me some rough translations of the errors. Thanks!

Thanks for giving me this information. All of your reported issues are now fixed for Beta 11, which should be released today.
