Has anyone had problems with these...I was accepted for the survey and took about 25 minutes of it and then all of a sudden it said I didn't qualify. I did not leave the survey and I put the correct answer when it prompts you to put a certain number on a line (to make sure you are paying attention and actually reading the survey). Anyone else have problems like this. It makes me want to not try to take anymore of them because it is a total waste of time.
