I need the flexibility of being able to work either on my iMac or on my laptop, so I eagerly purchased RW7. It took a little bit but then I was able to move the Addons folder to Dropbox. Also I saved my RW7 projects to Dropbox. However, when I open RW7 on my laptop, I get a message in the corner of the edit window telling me “Click Here Buy Stacks.” Obviously I bought Stacks a long time ago. What’s going on? Thank you.
