The CCO website has the file to be downloaded named vpn30xxboot-4.0.Rel.hex. I have renamed it in order to upload it to the concentrator. Now that it is on the concentrator, named vpn34Rel.hex, I've tried renaming it to vpn30xxboot-4.0.Rel.hex, but get invalid file name. Any ideas? I need to do the update today, so any suggestions are appreciated.
