So I have recently changed my minecraft account to the Mojang one but when i try to log into the technic platform it only tells me that my password/username is wrong does anyone know what to do!

So I have been playing this mod pack for a few days when all of the sudden it crashed so i tried to load it back up again but it wouldn't load. I tried to reinstall the mod pack but whenever I click install after it's done it still says install even though the mod pack is in my library so can someone please help me!
