SMS Problems!

[bhs_tigers_00]

Ok guys, so I came across the threaded SMS app a while back, followed the instructions which required me to delete a poutlook file or something of the sorts only to later realize I didn't need to delete that file but everything worked fine for a while.

But now, everytime I send a text message in a conversation, it sends the last message from every conversation I have saved in my text messages back to the person in that convo.

What would be the disadvantages of doing a HARD reset, setting my phone back up to factory, and starting from scratch? Would I have to re do all my contacts or would they be fine since they are in my outlook (via activesync).
