Hi, first of all sorry for my english. Many people have the same problem like you, but I finded a solution in one discussion. When you start your Wherigo player you have to be in free space that means no in the bulding so the gps could find signal. This causes because of the internal GPS has for 2 different things the same meaning - the internal GPS couldn´t tell us that it is finding satellites for fix, it can only annonce that it is fixed, or not fixed. So that´s why you always get the error messages. So go somewhere where you are not surrounded by trees or buldings then start Wherigo player and hold on. It can take several minutes. Trust me, it´s gonna fix satellites. This solved my problem, i have the same PDA as you Asus p535. If you have any other question just ask me i´m gonna try to help you.
