An error occurs when starting the downloaded client

Hello,

when I start the downloaded client, I get the following error message:

Error: System.IO.EndOfStreamException: Beyond the end of the data stream cannot be read.

What do I have to do to avoid this error?

Hello,

I have tried a little and then came to the conclusion that you have to take the English language with you when downloading the client. Then the error didn't occur anymore.
