Hi,
I m Fabrice from VSO, sorry I don't speak Polish, we only identified this problem today, and we know how to fix it , it is a stupid corruption of the translation file. If anyone speak english and would like to receive a free license and help us to improve the polish support , just download the version from :
http://download.vso-software.fr/copytodvd4_setup.exe
then with explorer, go to the LANG subfolder in the application folder, and run the langtool. from this you can edit the translation, update and you are welcome to post a new translation as an attachment , or contact us by the support form ( or private message )
thanks by advance
