If you send the MAC address for the active network card and the serial bnumber being used in the private message section when replying to this thread, I can generate the license file for you to manually activate design extender.
On windows, To find out the MAC address:?
1) Go to the Start Menu -> Run. Type "cmd" and click on OK to bring up a command prompt.?
2) At the command prompt type "ipconfig /all > c:\\ipconfig.txt"?This will create a file in your C drive called ipconfig.txt. This file will have the MAC address in it.
On Mac:
1) Open System Preferances
2) Go To Network
3) in the list of connections, select the active one, and click the advanced button
4) Go to the Ethernet tab and note the Ethernet ID
