Project M with cBliss problem

[Syeo]

Hi there,

now using Project M is the right decision, it's much more fun to play it.
So I added cBliss but I still have one problem: When using the Costume Manager, I can see that everything for every character is available. 10 pacs with pcs, 10 CSPs, 10 battle portraits and the CSPs for the result screen.
However, when being in the game and choose a stage, it doesn't finish loading. Everything is there where it should be, even the stock icons, but I can't play the characters.

Is it because some characters I added aren't compatible with Project M?

I remember reading back on the official PM thread here on the forums that the Alt. Costume Engine is incompatible with Project M 3.0+
