I have trouble updating my SLES 10 SP4 OES 2 SP3. It seems that even though it successfully registered with suse_register the update sources are missing.

zypper sl
only shows the initial installation media:
# | Enabled | Refresh | Type | Name                                                | URI                         
1 | Yes     | No      | YaST | SUSE Linux Enterprise Server 10 SP2-20090904-100100 | dir:///media/install/sles10/
2 | Yes     | No      | YaST | Novell Open Enterprise Server 2 SP1                 | dir:///media/install/oes2/  
What can I do to get the proper update sources?

I found tried to follow this guide: Support | Updates catalog missing after registration of OES2
But it fails from the start, there is no "/usr/lib/zmd/query-pool products" on my server...

Greetings, Mike
