Can't launch KHP since the upgrade

Did you reboot after installing?
I'm not an expert at the program, but don't you need to select the audio part first, then add the lyrics?
For the minimized problem, right click on the icon on your desktop, go to properties and see whether it is set to run in "normal window" or "minimized" It should be normal window.
It is resizable. Look in the upper right corner next to the close "X". It should have a single Box. If it shows two boxes then it is Maximized and you will need to click on it to shrink the window.
