I try to download apps onto my phone (Nokia E73) however it keeps telling me "certificate error. Contact the application supplier" and then Nokia Suite says "There was a problem with installing the file. Error Code: 2153775105."
I don't understand why this is happening, it happens with all the apps i download and all the apps downloaded are .sis files. helpppp?

ALSO: im trying to download an app via the WAP site...but when i write the address it directs me to the "enhanced" wap site and it does not recognize my login/password. Everytime i enter my log in information nothing happens, and it goes back to the log in screen? i am sure im writing my log in info correctly

PLEASE HELPP !!
