Anyone try to download the paid version of TweetCaster? I was using the free version, but decided I liked it and used it enough to pay and get rid of the ads, but tried several times yesterday and it would just say "download unsuccessful." I tried other apps and they were fine. I emailed the developer, but just curious if anyone else is having difficulty with this. I love that app because I can track all 4 of my Twitter accounts very easily and I like the interface.
