Access to my files when my Dropbox account is full?

This is very strange. I've tried several times to examine the contents of my dropbox, and always got stuck. This morning it opened right up. I've downloaded all the smaller zip files. The largest download won't open for some reason, but I know what it is and can request it from the owner again if my second try doesn't work. Once I either have it (a half-hour download) or have decided to abandon the effort, I'll delete it from my dropbox, and then I should be unblocked. I don't understand what the problem was, but since I can't reproduce it and the problem is apparently solved, I'm all set.
