Check your credit amount. Credits are missing.

So I had 800 credits on my account from my preorder purchase.
I just got into the game, started playing decided to check out the marketplace, didn't purchase a thing and I look at how many credits I have. Credit Amount 750
I'm thinking, "That's weird" is there some kind of rollback going on?"

So I go to the Glyph main page, log into my account aaaaaand: 0 Credits
Was there something I'm missing when participating in this PTS?
