Dear Madelaine,

Did you check this MT4 link? https://download.mql5.com/cdn/web/metaquotes.software.corp/mt4/mt4setup.exe?utm_source=www.metatrader4.com&utm_campaign=download

Its working for me. If it does not work for you, please check different browser or Google MT4 Demo and download from any broker with a demo account.

If you mean you cannot download our SphereTester Tool, then let me know your email.

Kind Regards,
Aayush
