When I try playing chess with a bot, i'm asked to download the stockfish chess engine, but when I press yes, I get, Download error: 304

Hello,
can you try deleting and re-downloading the existing engine on your computer?

To do this, press Windows+R to open the run dialog, and type %appdata%\QCGCWX30

Once this folder opens, delete the file called stockfish.exe (you will need to close the Playroom before doing that).
Then, try to play Chess against a bot again, it should ask you to download, and this time it should be successful.

Currently I'm not sure why this error appears for some people, but manually deleting and then re-downloading seems to help.

ok thanks, your suggestion worked
