I don’t think there is a problem with the theme, we never had such kind of problem/error messages. Our theme does not use API requests. I think the problem is your anti-virus software. What software do you use?
No worry, if you crash your website or the theme you can reinstall it always without any problem, also the demo content, there is no problem. If you want, you can send us (info @ 7theme . net ) a login for your website, then we can take a look at it.
