I keep getting a pop up message about a software update every 24 hrs on my HR24-100. The strange thing is, when I try and select "ok" or "cancel" it won't select either. I have to wait 30 seconds for the message to go away. I think the message says the version is 00135, which doesn't look like a traditional version name. Has anyone else seen this and is there something I can do to remedy this?
