If you see "invalid license" message on the login screen of Oempro, it's because the license.dat file has been generated for another domain (or sub-domain).

Please check the following:
  1. Login to your client area
  2. Go to downloads
  3. Check the domain which you have registered for the license.dat file
  4. Now, go to your Oempro admin area and compare the domain with the one in your license.dat file. They should be the same.

For example, the following will trigger the license error:

www.yourdomain.com and yourdomain.com http://yourdomain.com and yourdomain.com http://www.yourdomain.com and yourdomain.com

In order to generate a new license.dat file, go to your client area > downloads section, delete the existing license.dat file and create a new one.
