Problems logging in to the launcher

I downloaded the launcher from the site and run it and I get an error. I hope someone will help.
Error:

Looks like their is an issue with reading the preferences from your windows user directory.
What is your windows username? It looks to be completely non-ASCII character set.

"Nerds have a really complicated relationship with change: Change is awesome when WE'RE the ones doing it. As soon as change is coming from outside of us it becomes untrustworthy and it threatens what we think of is the familiar."
– Benno Rice

None ASCII Usernames cause issues and hard to fix that
