PIII controller iPhone app

[Newbies]

Not sure if this is the right place to place this but I'm looking for people with experience sucessfully setting up thier PIII controller/data logger. Im using a Windows xp based PC with an ether net cable connected to a Telus smart hub 3G router and the newest version of the Iphone PIII controller app. on a iPhone 3Gs. I'm not the best computer skinner but have found the IP on the Profilux, entered it on the Marinmad web site and all my other info and when I try the Data logger program on the computer all it says is invalid credentials. When I try to connect via the iPhone app all it says is loading untill it kicks me out due to timing out. I hope someone out there has something for me to try as I'm getting really frustrated. Thanks in advance for the help
