Okay, so recently Mojang updated with a bug fixing patch. Because of this, players with their profile set to "Use Latest Update" will not be able to log in. To fix this issue, do the following: Start up minecraft launcher Look in the bottom left hand corner of it, where you will see your profile Hit "Edit Profile" Go to where it probably says "Use Latest Version" or "1.7.6" Click that dropdown menu and select either "1.7.4" or "1.7.2" Then hit save profile, and start playing on mineverse again! Hope this helps those that were confused.
