When I clicked download button, No Response,Why?
Is that China area limited download from this website?
If you have links used/screenshots/browser console error messages someone might be able to help you.
Otherwise you will to have to troubleshoot yourself , do you have the option of a VPN? Have you tried a different computer on the same internet connection?
I know why now, cannot download on Chrome and Edge brownser, in other brownser(360 or sougou), download is OK. Not this website problem.
