Need 1.28.0 game files

Recently I posted this thread
Possible to roll back to 1.28 and asked if it is possible to roll back the game to 1.28.0 since I need to watch some replays. I also asked on official Blizzard support website but I didn't receive an answer.

The user @TriggerHappy said that it would only possible if someone would give me his / her gamefiles.
Since I haven't found a solution to rollback the game I am asking if someone is willing to share me his gamefiles for 1.28.0. You can change the keys to some arbitrary banned keys, i don't care because I only want this version to watch some old replays.

Thanks in advance.
