I'm having the same issue at 26%. I'm going to keep an eye here to see if any solution comes around. In the meantime I do have to say with responses like the one Oldstone has above. This is a beta and its here to fix these sorts of things. The fact that you need to say "they'll never learn" and the whole "lose customers" bit. They don't owe you anything... you're the one that chose to participate in the beta for free so please get off your pedestal and take your negative attitude elsewhere.

Now, I look forward to this issue being resolved soon. Thanks for making this post to know I'm not alone with this issue.
