How to download Topping DX3 Pro Drivers from Topping website

I´m going bananas trying to download the latest firmware upgrade and drivers for the DX3 and I´m gettin´all the time this message:
' Too many requests
Sorry, this link has been automatically turned off for now. Learn more about traffic limits.'

How in hell i´m going to install the drivers when DX3 Pro arrives?

Has anyone got the drivers and the firmware upgrade to solve the `clicks' when changing source?
I would be eternally grateful... My Email address is :
