CrazyClient Help

I downloaded willfuttbuck 20.1.0 crazy client. and its the .rar file but it doesnt do anything when opened. Any help?

You extract it and then you should get a .swf file. You then run the .swf file with your adobe flash projecter (I'd recommend getting 13). You might also want to run the LangFix.exe file if you have never used crazyclient before.
