I deleted froge and completely reinstalled mc because forge client wouldnt see mods and now when i try opening the forge thing cmd opens and then closes instantly. I installed the java thin g again it is still broken. So then i uninstalled everything from mc to java to forge and reinstalled it and forge still wont open with java like it did. I uninstalled forge because i wnted 1.12.2 and got 1.12. Anyone know what i should do?
