Is anybody else having this issue? I seem to having issues with the Mac App Store on both my Mac Pro and Macbook Pro after updating to 10.7.3 I'm unable to download (or re-download) anything. I just purchased an app (and not a cheap one) and the download didn't start. I go into purchases and (after quite a while) the list shows with my purchased apps and all of them (even the installed ones from earlier) have "install" next to them, without the underlying image (so it looks pretty bad)... but clicking does nothing. I tried on both computers thinking maybe its isolated, but I have the same issue on both. on the macbook pro, the purchases page actually looks much worse and like its missing its style sheet.
