You will need to migrate your account and licences to the new server
To do this create a new account by clicking the Sign-up option top right
The important bit is to use your old login details when creating a new account
Once logged in to the new site, click My Profile and select Migrate your Old Data
You then will be passed back to the old site to confirm the migration with your username and password (remember you didn’t change them)
Once completed all your old licences will work and you can log in to the DH software (Latest Version is 1.41)
