I am also having this same problem. It happened when I tried to import some lossless WMAs, TinyHTTP.exe (The hideously-large, memory-resident, ironically-named piece of shit) performed an illegal operation or something like that and from then on, Connect would not load. I'm not too impressed with Sony releasing such unstable software, it isn't even labelled as Beta but I know far more stable programs which are labelled as Beta.
