Due to multiple database migrations during years, some licensing conflicts have raised these last days. To avoid any mass error we handle each one manually, not a big problem but as I saw many requests in many different threads, and as I like things to be clear & clean:
Please forward me your license number via "Personal Message".
I will have a dive in the database, fix the issue, and get back to you asap.
When it's done, remember to get your activation code as described here (http://www.arturia.com/evolution/en/community/arturia-helpers), and authorize your favorite synthesizer as described there (ftp://ftp2.arturia.com/pub/manual/Register_and_activate.pdf).
