Somebody please help. For several days now I've been trying to download Yosemite PB2. Every time, I get Error 1004. Some things that didn't work: deleting preferences and cookies, switching users, booting from a different disk. Anything else under Purchases, I can download fine. I tried asking on the Apple forum and they deleted my question LYING that it contained information about the beta. This is obviously absurd, since the problem is with the store and anyone who read the post could plainly see I couldn't even get the beta in order to find anything out about it to reveal!
