Venitas

I recently downloaded Technic launcher so me and a friends cold play Pixelmon together. When I am in the login screen and try to login using my Mojang account It either freezes or refuses to log in. like when i click the "log in" I will not try to log in, or it say invalid Email/Password. I can log into my Mojang and Minecraft Launcher just fine and even changed my password and it still refuses to let me login. Me and my friend have been working on this for 45 minutes and still have gotten nowhere...
