When I launched PSO2 from my taskbar to change some graphic settings i hit no by accident, after that when i click on the app icon anywhere it wont even open the launcher, there is no error codes, no messages that say "failed to connect" just, when I click on the open, or open as admin nothing happens,. I can't even uninstall and reinstall the game it just won't let me. Any advice and help would be appreciated.
EDIT: I was able to fund the problem, the main problem was an old anti-virus software i had on my pc that wasn't uninstalled, now I am able to enter the launcher, i recommend if you are having the same problem to see if there is any 3rd party anti-virus software running in the background
