Thanks I tried contacting support, and your instructions worked. However I got no joy. They told me that although I had paid for a perpetual license 4 years ago and been using it, they Key they claimed was subject to some fraudulent activity. So after a very long conversation, I was forced into a DW CC subscription for an an additional £240 pa. A really great way to treat a loyal customer. Very disappointing given the fraudulent activity was nothing to do with me.
Does anyone know of a good substitute for DW on Mac, with a migration path to it ? I want the DW capabilities for managing and creating websites. Thanks Jon
