Hi I am using XAMPP on Windows XP. Since I changed the version from 1.73 to 1.77 MySQL does not start properly. That means that the status says, it is started, but the safety check says it is not . Because of that I cannot set any password, which is unacceptable.

Any idea?

That's mysql_error.log:
