There really is some problem that is causing difficulties - the helpdesk is doing it's best to figure out what is going wrong in my situation. Just wanted you to know that you are not necessarily doing anything incorrectly. I've gotten - oh, say one in five to download in a reasonable length of time, out of purchasing the whole library. And not having trouble with any other site
Because of all of the clicking, I exhausted many of my links, and I asked about the three click limit. I was told that they'd reset mine. Just be sure that you keep in touch with the helpdesk about what's going on. Mostly I hear back within one working day of a posting.
BTW, I wouldn't let this discourage you from purchasing downloads. It just sometimes takes awhile to get the bugs out of any network system, and it's especially hard to diagnose them when one end is a commercial organization, another is a user's home, and the person trying to fix the situation is at yet nother site! I'd guess that this will be smooth sailing after awhile.
