After 30 Days of trial expiration, can we be able to activate DarftSight software? 

If yes, can you please let me know the detailed steps.

In my case it was expired and for your information my machine is in domain network. i tried to add proxy server settings and click on apply and ok and i save the file.But the proxy settings are not saved, So still i am not able to activate because the fields are greyed out. Any suggestions would be appreciated!!
