View replays of versions earlier than patch 17

IMPORTANT: Upon the latest patch 17 beta phase #2 it seems now impossible to view any replays from earlier patches. So here's working solution: just find the folder "Base16036" under your local path of StarCraft 2 (mine was "E:\StarCraft II Beta\Versions") and move it anywhere outside current directory (e.g. to your Desktop). Now to watch replay find "E:\StarCraft II Beta\Support\SC2Switcher.exe" and drag replay file right to it!
DON'T forget to put folder "Base16036" back when you ready to play a new patch @ Battle.net!
P.s.: You could simply rename particular folder to something like "XXXXXBase16036" and then put it original if want to play at b.net.
So if you curious on how to play sc2 replays from different version it's for you!
