A few questions,
Have you set the net-7.org launcher and the EnB Client Executables to run as administrator and also compatibility mode, also do the same for the EBconfig exe file in the EBconfig sub directory in the EnB game subdirectories?
When you start the launcher have you moused over the net-7 icon on the task bar to see if it started as a minimized window, if window pops up when you moves over then right click and select maximize, (you can adjust the size of the window later if it pops up, if the EnB window does the same thing hover over task bar icon right click on mini window select maximize again, if the game window is not to your liking Navigate to the EBconfig directory and select and run the config program and play with the resolution setting until you find one you like make sure you run the test to set the resolution.
