Im trying to open the launcher and a window opens saying ''updating minecraft launcher'' and a loading bar, but when it finishes loading the window closes and when i click the launcher icon the loading cursor appears for a few seconds but the launcher doesnt open. I have tried changing the compatibilty settings and some other things in the properties but nothing happens. This has been happening to me since the last launcher update where skins were added to the launcher (about 3 days ago). Please help me or fix it.
