I am unable to download from wherigo, the app keeps telling me to check username and password which I have reentered many times.
Sorry for the late reply... forum notifications weren't being sent for posts.
Did you enter your login credentials in WheriGO Settings? Those are just sent to the wherigo.com website for authentication. Be sure you can login on that website. You could also try the WhereYouGo app to see if the login works there.
