So you've entered your address and you come to the conclusion that your latitude & longitude might be wrong. This can happen, the first thing you should do is see if the address you've entered is correct.
Also make sure your address is findable by google. To make sure you've entered a correct address go to Google Maps and enter the address there.
If that does not work send an email to info@pigero.com and we will sort out the issue for you.
