Ask the people at the store the same questions you are asking us. If they can't help you, then they are in the wrong for not selling you a working product. They should be obligated to give you a free new on, or give you store credit worth more than what you paid.

Important thing is to talk to a manager. Ask to speak to a manager as soon as you get there, if one is not there leave...

hiya i recently bought a used copy of nintendo ds broswer...well its basically a thing where you can go online via ds if you have a wifi connection...but the d-bag who sold it to the place i bought it from didnt give them his ols password...im stuck at the beginning and cant go past because of the password protection...if anyone has this is there a way to reset the password to my own...its pissing me off that im just thinking about returning..that seems like the better option and just buying a new copy instead...
