Dragon Age Origins: Where is Oghren?

I'm playing Dragon Age: Origins with Windows 7 and NVidia 550, also 4 Gb of RAM.

I installed the first time, played the first time through (badly) and recruited Oghren.  Decided to have another go.

Loaded the Shale DLC and started again.  Oghren had disappeared.

Uninstalled the whole thing, reinstalled and played again without the DLC.  Oghren appeared briefly to have a conversation with a guy, then disappeared again.

Uninstalled, reinstalled no DLC, no Oghren.  Applied Patch Version 1.05 annd started again, no Oghren.

Where is Oghren?  Anyone knows?

Thanks!
