Was that through the Survey Tab? I was dq'd after about the 2nd question on two different ones there today. It happened so quickly it wasn't the problem you had. Occasionally what happened to you happens to me and you're right; it's very frustrating and bordering on fraud to entice with payment, collect the info and then kick you out at the end. Contact the survey company directly in addition to Peanut.
After the 2 quick dq's I didn't try any more there and picked up 75 credits on my first attempt at MyView through the Offers tab instead.
The videos for credits and views all worked correctly for me today.
