So you were using 0.4.7 before 0.4.8 came out, it worked fine, and now after installing 0.4.7 again you can't use it at all..? No idea what is happening there.
When you say crash reports, do you mean GameTranslate crash reports or something else? If they are GameTranslate's, please do click 'Send report' on it. If it is something else, I'd very much appreciate a screenshot of the crash report window.
Thank you for the information.
