Script Error on startup with zwift.js

When I start Zwift I get this error I can click yes to skip over it but would like to fix it. I’ve reinstalled Zwift (cleared all directories) but it still errors.

Hi Russel,

    Can you let me know what Operating System (OS for short) and version you are using and what’s the version of the OS native browser (IE or Edge on MS Windows or Safari on Mac).

Thanks

Windows 7

IE 8

i have the same error Windows7 64Bit.

what do i have to do?

 

crashes after i click on ride

it seems that several updates of my fresh windows7 installation solved the problem
