Error while buildig a downloaded cBot

Hello,

I successfully downloaded the ZelpynSclaperII cBot from cTDN but when I try to make a change to the default volume value and click on Build I get the following error message "Error : Project C:\Users\.....\Documents\cAlgo\Sources\Library\cAlgoLib\cAlgo.Lib.csproj doesn't exist." and I cannot used the cBot.  I am new to the use of cBots and was wondering if thereis something I am missing
