I have bought from Extend Studio, "Flexi Lightbox" and "Flexi Menus 2 Bundle" for DW CC. After Upgrade to DW CC2014 and latest Extension Manager i can´t install Flexi Lightbox. The Extension Manager says: Cannot install the Flexi Lightbox not contain a valid Signature. Please help... what can i do?
Under the circumstances, I would ask the kind people at Extend Studio
All you have to do is to open the Adobe Extension Manager CC and go to Tools> Preferences and uncheck the "Allow Extension Manager to access Internet" option.
In this way Extension Manager CC will not check certificate revocation information from Internet. After installation please check this option again to avoid security risk.
