Problem installing Main Demo

I’m trying to import the Main Demo and it just sits there with the loading circle and says “Please be patient while Highend Main Demo demo is being imported. This may take a few minutes.”

I waited almost 2 hours and it still didn’t install so I think there must be a problem but I’m not sure what it would be. I use iPower as a host if that tells you anything. Any advice would be appreciated. Thanks.
