Occultist archetypes and Outside contact

[MusicAddict]

Can an occultist who loses the magic circle class features still use his outside contact ability if he still has it, such as with secret broker?

My assumption is no because outside contacts wording implies that you habe to be using the magic circle class feature, not a magic circle made by a spellcast or ally, and in which case, how does secret broker use outside contacts?

Unfortunately, the errata for occult adventures is't out yet, there are a lot little issues like that. They haven't been officially addressed yet.
