Cross Class Skills help!

[Dgsoil]

I'm a lvl 16 Conjurer and I lvled up to 7 Thaurmaturge to get Thunder... but it won't let me use Thunder as a Conjurer... my gear sets say I'm only lvl 10 conjurer and lvl THM, but that isn't the case... what am I missing and what do I need to do to get cross-class skills?

I can use cure as my lvl 7 THM though... I have the 3 slots on CNJ but all the skills are greyed out...

They just changed it so Thunder is no longer a cross class spell for any class now in patch 2.1, that's why you no longer have access to it
