App Store OS X 10.8.5
I Just did a Clean Install of OS X 10.8.5 on my 21.5 Inch iMac Late 2013 and Want to Upgrade it to OS X Mavericks which is in my Purchased Tab on the App Store but When I click on the Tab it says "We could not complete your App Store request. The App Store is temporarily unavailable . Please Try Again Later". I have tried signing in and out of the Store and No luck. Everything Else works ok except this.
iMac 21.5″, macOS 10.12
