Errors whilst ripping with UE Viewer

[saratogaroad]

Have you checked the UE Viewer/UModel forums? Because they have a topic on Gollum, and apparently you need to be using a game specific override version, not just the one you can get on the main site. Check the link and go from there; they're also probably more likely to be able to help with your error message, too.

It might also be worth trying FModel, though I wouldn't know where to begin on how to use it with Gollum, specifically.
