Did you use it in English or with another Language?
Here it looks like the selected language is Belarussian or some other non-Latin alphabet, but on a system set for a Latin character set.
If you were using it in English, you maybe accidentally changed the language: on the 4th (last) tab of that window you can select another one. I mentioned Belarussian as it is the 1st of the language list. Maybe there is a bug that made that language selected though.
