The thing is it looks like you've restored the messaging app from your nandroid to your current rom. I don't think they are compatable, you'll have to dig around in your current rom zip for the original app and replace it, alternatively you could just clear cach and dalvic and reflash seeing as you only did it an hour or so ago. With regards your messages, titanium can back up your messages and restore them to whatever rom your using. Rather than restore the app itself, try just restoring the just the data. It's a powerful app but just needs a bit of care what you do with it. Not all system things should be restored.
