The left screenshot tells a sorry story. This is the Nokia Store on my N8, shot after a two week period of trying to install three games. Note that small applications, a Megabyte or so, download and install fine, but anything vaguely large (e.g. a decent game) fails every time. And I'm fed up. What must a normal user feel like at this point? I reckon I've now tried downloading Angry Birds Rio about 30 times without a single success.
What seems to be happening is that the download is failing at the server end - some kind of transmission handshake breakdown - when handling large files. And it's surely a bug, since this was far more reliable a few months ago.
As with the previous Nokia Store woes, this is undoubtedly a case of the diminished attention being given within Nokia to Symbian-related resources - but I'm still hoping that the problem is diagnosed and fixed promptly - after all, a life without Angry Birds is not worth living, surely?(!)
Comments welcome if you've also had these errors for longer downloads from the Store...
