A couple crashes and now it don't work at all. (I use Blogger & b/c of LifeCast I added Utterli. But now I can't seem to hook EITHER site up!)

Sleepy Dogs, I really like Lifecast ... but it was crashing. I uninstalled & re-installed, but the app hangs when I try to add a Blog. It says "downloading settings..." and that's it.
Any suggestions? Using a 3G iPhone and your newest version. thanks - rekzkarz.com
