Can not install or update on the Mac App Store
I can not update or install new apps. Some work though, some do not. For example I can update GarageBand and UberStrikeHD(2 random apps that I have an update available for) and I can not update LevelHelper and Trillian(also just 2 random apps I have an update available for).
As for new apps ... Well, all that I tried they didn't download(ReadLater, CodeCollectorPro and RamOptimizer Lite, Apple Configurator are 4 of the apps I tried downloading). I get to enter my password, the app "goes" into the Launchpad, but the bar that should show the progress of the download gets filled instantly and the Appstore shows "Installed" instantly, while the Launchpad icon also shows the bar full instantly, but the app is obviously still greyed out since it didn't really download anything. Then after a few seconds I get an error:
"The application could not be downloaded. The requested URL was not found on this server". Cancel or Retry, retrying doesn't work either.
I am using a broadband internet connection, but I tried it with several USB devices and I got the same result (also tried sharing the broadband connection from a macmini and connect to it through internet sharing, still didnt work)... And I do not have 10.7.3 installed, since it is a 2GB update and my broadband data plan is capped at 4GB, but I doubt it will fix anything, since in the past I got this error before, but I have no idea how it got fixed. I also tried every Apple provided support article.
Console log shows 3 errors, as follows:
