Upgrading from Version 1.8.0 to 1.8.1 :

Due to a bug in v1.8.0 installation requires the following action :

1 Download the Version 1.8.1 installer from our website.

2 Run the v1.8.1 installer. 
  (this will install the new version, but certain parts will not update automaticly)

3 Run the v1.8.1 installer again and click remove. 
  (your license key, forecasts, game data, etc... will not be removed by this)

4 Run the v1.8.1 installer again. 
  (all parts will be updated properly now)

For future updates, this action will no longer be required.
