Doesn't work for me. All I get is a black screen. I repeated this a couple of times now. extracting last version into a folder, updating the www folder from current update.... black screen.
There are two ways to do that:
1) Download the full Linux (v51..) version and the full Windows (v54..) version. Delete the Linux's "www" folder and copy over the "www" folder from the Windows build.
2). Download the full Linux (v51...) version and the Windows update-only files.
Do not delete the "www" this time! Extract the update-only file's "www" folder and
merge the files with your Linux "www" folder.
Note:
Don't try to apply compressed files on a uncompressed build or vice versa! It won't work.
Compressed game requires compressed files and uncompressed requires the uncompressed (original) files.
