Hi,
You can change following sentence in ~\CMSResources\CMS.resx (flash.notsupported):
You have an old version of Adobe's Flash Player. <a href="http://www.macromedia.com/go/getflashplayer/" target="_blank">Get the latest Flash player</a>.
Please note: This change requires restarting of the application from
CMS Site Manager -> Administration -> System section.
I’m very sorry for this inconvenience, we will fix this bug.
I hope this will help you.
Best regards,
Miroslav Remias.
