Solution Manager System Copy

Hi Gurus, I am stuck with the SUM(Software Update Manager) it tells me the following:

"Enter at least the mount point containing Export DVD for product CRM/SOLMAN".

Now I have downloaded the following Software from SWDC:

1. 50104958
2. 51042608
3. 51042609
4. 51045452
5. Solman_7.1_SR1_Krnl_Windows_OS_400
6. 50116982
7. 51042010
8. 51042607
9. 51042616_8
10. The SR1 Solman Upgrade Export 18 DVD's are getting downloaded.

My System is Windows x64, Oracle. Source Release SOLMAN7.0 EHP1 and ST21

Please somebody let me know do I need to download some more stuff or this is suffiecient and why is the SUM stopped at provinding Mount Point.

Thanks
