Help Me Please!! Help Me Please!!!
 

I have a t-mobile wing and installed the palm threaded sms from wm6 rom. During the installation a problem came up it stop installing. as i kept reading i saw a zip for the t-mobile version which i installed and s/r the program was there but didn't open just the loading wheel thing then it closes the window. so i uninstall it and now i get a error message

"the file 'messagingapp' cannot be open. Either it is not signed with a trusted certificate, or one of its components cannot be found. if the problem persists, try reinstalling or restoring this file "

now if someone can help me i would highly appreciate it
