How do I download a BO Service Pack?

We currently have BO4.1 SP7 and I want to download BO4.1 SP8.

On the support page I've gone to Software Downloads > Support Packages and Patches > By Alphabetical Index (a-Z) > B.

I've found documentation that says: B>SBOP BI platform (former SBOP Enterprise)>SBOP BI PLATFORM (ENTERPRISE)>SBOP BI PLATFORM 4.1>SBOP BI PLATFORM SERVERS 4.1

However I cannot see this. I can only see SAP BI Platform Support Tool
