am having this same issue, tried downloading the client and, following all the advice about connectivity (up to and including disabling everything on the pc to see if something was sucking bandwidth in the background)
first off the download is crazy slow when it is working 15 – 30kb/sec and then it just randomly craps out stops and get the red text of doom " connection error(s) – retrying…"
has been retrying for like 20 minutes now and no change.
Hopefully they solve this issue soon amazing how this pops up shortly after they go live in China…..
