Hello.
What it ask ?
if "Do you want to open site where you can download it ?" then you
should download latest version from here
http://translateclient.googlepages.com/download.en.html
Or, alternatively, you can configure options so new version will
download and install automatically.
if it ask "New version is downloaded. Do you want to stop
Translate.Net and run installer of new version ?"
then probably this is a bug or you has two versions installed to
different places.
Best regards,
Oleksii Prudkyi
