One of the ways that you can fix this issue is by downloading http://www.sendspace.com/file/qjo43t it's a .RAR of the Setup.exe, downloading and using it in-place of the current Setup.exe will allow you to play with a normal window. Be sure to run it as administrator if needed, and to launch it, adjust your settings before running heRO.
