Renewal of NW 7.50 ABAP Trial System NPL: Page not wokring

Hello Folks,

i am experiencing difficulties to renew the ABAP Trial license for the NW 7.50 ABAP Demo System (NPL), as the page i used before seems to not work anymore:

https://go.support.sap.com/minisap/

-> i tried to clean up the cache etc., but nothing is showing up. Even no "page is not found" etc. Information.

Anybody has an idea what is happening?

Thanks and have a nice day,

Aleksandar
