'Install' button under Purchases doesn't work.
I recently wiped my MacBook Pro by using my old Snow Leopard discs (I was on Mountain Lion), but now when I try and upgrade to Mavericks via the App Store, absolutely nothing works. Going under the 'Purchases' tab shows all my past purchases, but when I press the 'Install' button next to each, I get a spinner briefly, and then the button switches back to 'Install'. Nothing ever downloads. Please help, as i'm now stuck in Snow Leopard and can't download any apps I own, let alone download Mavericks OR Lion to upgrade back to normal again!
Any advice would be greatly appreciated!
Many thanks.
