hmm, registered a copy of m&l dream team but it gave me an error after filling out the survey.
when i tried registering again it says that my pin has been used.
should i wait or contact customer support?
Happened to me a bunch yesterday. As mentioned you can either wait a bit for the survey to populate in your to-do list, or just back up a few pages in your browser to when you first started the survey(the first screen after putting the code pin # where you enter your age, etc... and it pops-up a window with your saved preferences pre-survey questions)
Re-enter that stuff(or choose your saved preferences from pop-up window again) and go to next page and it should let you fill out the survey again with a blank form.
Should let you finish now and get the coins. (Just do continually if you get another error message after submitting, better than waiting on the to-do list petrified that it won't happen)
Oh and ALWAYS WAIT FOR THE SCREEN TO SHOW YOUR BEFORE AND AFTER COINS WHEN FINISHING A SURVEY!!! You will notice the webpage is still loading information after the survey mentions it being 'finished' It is loading your coin count(shown with an image after 10-20 seconds) and I've had a few hiccups when I jump right into another pin# instead of waiting for that coin confirmation to populate on screen.
Added about 1200 coins from ancient DS games and Wii titles I never added yesterday, so I hit a LOT of errors and such making sure everything got sorted. Shame that I missed out on DKCR, Metroid Other M, and a few others due to those pin's expiring late last year(expiration date in fine print on the pin insert).
Hotel Dusk, Brain Training, and several older games from ~2006 still accepted though.
