why some replays don't work for me?

[deleted_player]

Hello, i was trying to see some old cringy/embarrasing replays of 2014 when i was named "xnyancatsx", but only 3 of them worked, why does this happen?, also it's not the first time that this error happens to me

Upload an example replay that doesn't open so we can see it for ourselves.

Any chances you're just trying to open a v3.7.2.1 replay on v3.6.31.0?

Try to remname them to something simple as "111".
