Vision Client Launcher error message


I am getting the following error when trying to launch an application from the Vision Client Launcher. Is there a fix for this?
Have tried deleting the cache folder but it still won't launch.

“Error launching application:RuntimeException: The client version or cached module versions are not compatible with the gateway version. Please re-launchclient.”

This looks like its the same error as yours, try this.

My system isn't using redundancy.
I seem to have fixed it with a stop and start of the gateway.
