Download DESTiNATiON 5.00 Beta 1 (http://www.file-upload.net/download-530103/destination_v.5.00-beta.rar.html)
Your file host sucks big time.
I've just glanced at your script and a couple things jump out at me; you have multiple arrivals (I counted at least 3 ChatArrivals and several ToArrival and NewUserConnected functions). You would be better off consolidating these so you have one of each. Also you have a DataArrival which is an obsolete arrival function last used in Lua4.
