Via Internet Explorer i get an error message that there is a problem with the security certificates for this website.
Edit: If i am using Firefox i have no problems with the certification if this helps somehow.
Edit2: I found out what caused this error. I was using a Tool to deaktivate the telemetric monitoring of Windows 7 (XP-Antispy). Therefore i deactivated the download of certificates. Now after picking out the spoecific setting and reactivating of the downloads of certificates everything works. This includes the visites of the Site via Internet Explorer AND the activation of SVP 4
Sry if i caused any trouble through my own mistakes but thank you for your help anyways.
