I got the same problem: script restriction #44 whenever i try to join a server trough "play with six". And i can't join a server trough dayzcommander since i'm unable to update anything. Here is the error message when i try to update anything on dayzcommander: Failed: System.Net.WebException: The underlying connection was closed: An unexpected error occured on a received. ---> System.IO.IOException: Unable to read data from transport connection: A existing connection must have been shut by the distant host at System.Net.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer,Int32 offset, Int32 Size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(httpWebRequest request, Boolean userretreivedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Net.HttpWebRequest.GetResponse() at DotJosh.Dayzcommander.App.Core.ModInstaller.DownloadAndExtract() (the part "A existing connection must have been shut by distant host" is in french since im in France and is cut at dist but i guess it says distant) I've seen on the dayzcommander forum that someone had the same problem and that the issue could be the port 21 blocked somehow. I tryed reinstalling dayz commander, updating with windows firewall off and avast off aswell, I've tryed also to unblock port 21 and 20 trough the firewall but none of those option works.
