Converse with fellow players
Are you using PSO2 Tweaker?
You should try logging out and in again, as well as verifying files.
@coldreactive i have done that already and no this is not tweaker this is steam client the issue still the same
If the permit has not been unlocked by a character with 2 level 75s, you can't use it on other characters yet.
@FANtasyStarOnline he obviously has that, in the image is possible to see that he unlocked the other classes
the only thing I can say from this is send a ticket looks like this is a serious issue
