The new version 1.7.0.403 that included new GUI makes all of the current translation files become invalid, you can check it at 'Setting' menu, the tabs above still show english text, it was translated correctly in previous version. Beside that section many part of the program become not translated to any of other languages too like 'Summary' and 'Statistics' in Registry Cleaner, also the 'Open in Regedit' menu in History Manager is never translated correctly since the very first version of jv16PT 2007. Please fix this, there are also some spelling error in original english translation, like 'shortucts' lol.
Btw it seems there still other bugs even in latest final version of jv16 PT 2007, i hope juoni vuori realizes this and fix it as soon as possible. Thanks :)
