Seems to be an error with the authlib. Make sure your account-settings are correct. Try migrating old MC-only account to new Mojang-style account-type if not yet done.

After long process of getting the e-mail on the account changed to what it should be and getting the account migrated I am still having the same problem. I have found that 1.6.4 packs work its just the 1.7.10 packs that are giving me problems.
