When you are viewing WinGate from a remote GateKeeper you won't get access to the plug-ins or the history file unless you map a drive to the WinGate server and run GateKeeper.exe from that mapped drive.
The problem that you're seeing on the actual WinGate machine is probably caused by the Kaspersky key file being expired. You can download a new Kaspersky key file from our website here
. You need to restart the engine after replacing the file.
