Sprint HTC Hero :: MMS Not Downloading / Force Closing

I've tried searching for a thread to help me with this and can't seem to find one. My mms will not download to my phone. The messages come through but will not finish downloading or open. I have uninstalled handcent which I thought may have been a problem and it corrected it for 1 mms then I am back to square 1. My internal memory has 87mb left and I've deleted all apps I don't use.

I have tried deleting all messages in the phone by batch mode and it either freezes up or gives me force close to what looks like the mms program. I am trying to avoid a hard reset because we all know how much of a pain to reinstall everything is. I am starting to get really fed up with the phone because for the money I paid, I expect much better. As much as I dislike Apple products, I can see why people rave about their products - they don't have these problems. (*sssshhh don't tell Apple fanboys I said that)
