Help - Twitterberry running very slowly.

I'm using Twitterberry 0.8 on a Verizon 8330. The program suddenly started running very slowly. I get an hourglass for significant periods of time when looking at my "friends timeline" and once it loads the hourglass pops up for a second or two every 10-15 seconds. It has basically made the program unusable for me.

Any advice?

Thanks!
