Something happened on GF today that's never happened before.

Completed it fine, got the congrats page, then when I clicked "go to members area", when it came back to SR-the page said I wasn't logged in.

Do you think that GF will credit or should I try and take another one?

It's the one thing I don't like about GF, if something goes hinky, you don't know until the next day and by then it's too late.
