Factory App Restore Help!

[jokerjtb11]

Okay, well I tried rooting my Samsung Admire, and ended up "backing up" my Factory Messaging app and thought i could uninstall with there being no problem with sending and receiving messages. But i then noticed after trying to send MMSs through go sms pro they wouldnt send. So I researched and found out that I could download the apps spk file and its odex file. And i tried installing it back. But it keeps saying parse error. I don't know what to do now, can someone please help mee??
