I can not click anything in LimeWire

[TechnoFan]

I am starting LimeWire and it starts like usual. The window pops up with the option to upgrade to pro. I try to click later and it doesn't work. I tried to click the red "X" in the top right of the window and it won't close. If I right click and select close then it will close. After that when I try to select the type of file I am trying to download, it won't let me click. I can't click anything. I tried file (in the top left) audio, video, search. I typed something in and pressed enter. It searched but I couldn't click the file I was looking for. What should I do about this? I checked to make sure it was updated as well as uninstalled and reinstalled. Nothing worked.
