my SAP ER 2004 Installation Media. Vanished from SWDC?

Hello,

I need to download the mySAP ERP2004 Installation Master CD (desperatly).

But all mySAP ERP 2004 media miraculously seems to have vanished from

Installations and Upgrades - Entry by Application Group" SAP Application Components" SAP ERP

(I'm disturbed and confused. A state of mind becoming a quiet constant, since I call myself SAP technology consultant).

Cheers

Thorsten
