It's still trying to redirect you to the backoffice after login?
I saw a new million satoshis page, but I can't understand much of that. I registered on the first one but got nothig.
Could you explain a little more how to get the credits?
You just have to follow the instruction they give you. Offers can be very different. Some are for registering on some site, others to like some facebook page, others to download and install some sketchy software(only on a VM if you know what I mean).
Can't say for sure what happened in your case, without more information, like the offer name.
