Messaging Problem

[Deckard]

Today I got bored and tried to install the WM6_threaded cab on my Touch. I played with it for a bit. I didn't really care for it, so followed the instruction of a friend to uninstall. Well, I must have did something wrong, because every time I try to get into my messaging program now it says:

"The file 'messagingapp' cannot be opened. Either it tis not signed witha trusted certificate or one of its components cannot be found. If the problem presists, try reinstalling or restoring this file"

Our course my friend has no idea what happen, since he had no trouble removing it. So I am here to ask if anyone knows a way I can restore this?

If you need any other info just ask.

did you try restarting the phone? messagingapp.exe must be the process that that program was, but tmail.exe (correct me if I'm wrong) is the process that handles all messaging on WM6.
