Urepo pop up

For the past month or so I have been getting a Urepo pop-up that covers most of Kodi on start up. All it says is UREPO in big blue letters and “cancel” which I do, so not a huge deal, but it is very annoying. I’ve tried googling and searching in these forums but doesn’t seem to be any mention of it other than a YouTube post – “Kodi Urepo popup fix along with Install of Gorilla build” – but that seems like an unnecessarily complicated method of stopping the pop-up. Are there any buttons I can press or settings to change in Kodi that will stop this. I’m using 17.0-Krypton_rc3., which I have just updated to but it didn’t solve the problem.
