Hello

I'm using DraftSight for private use, but since the last update attempt to version 2015 I’ll get the error like

QMetaObject::connectSlotsByName: No matching signal for on_help_clicked()QMetaObject::connectSlotsByName: No matching signal for on_help_clicked()NOT SANDBOXEDQMetaType::registerType: Binary compatibility break -- Size mismatch for type 'QPaintBufferCacheEntry' [1024].

When I remove the update (zipper rm or rpm –e packagename) and install an older version I get the message (I use German language)Dieses Produkt ist nicht lizenziert oder abgelaufen.(This product is not licensed or has expired.)Do you have any idea how run the new or an older version? If I were to use an older version, where can I download this or reactivate the license?
