Uh, I think I did something wrong. I uninstalled it because something went wrong, It probably broke because of the registry. I tried to fix something that has failed and then I changed some registry to the app, then now everything went wrong. What have I done…?
Hello! 
Your issue is most likely to be caused by a security program on the PC or network you are using.
