Lack of interaction in Requiem

[welshofdave]

Just started Requiem and I have a few issues.

While I can drag blocks around, etc, I don't get the little eye icon for anything. I can't examine the switches, or the corpse, etc.
The books I pick up don't tell me anything and I can't read them.
Despite getting the sparkly sphere thing from across the bridge, I can't use it or the portal.

I eventually gave in and looked at a youtube video of the first level and all sorts of things are examine-able, and the books give some backstory when picked up, etc.

I get a lot of warnings and errors in hpl.log, e.g.

WARNING: Could not find language file category 'RequiemMenu'
Loading collada for 'expansion01/maps/level01.dae' took: 1395 ms
ERROR: Couldn't find particle system file 'particle_imp_dirt.ps'
ERROR: Couldn't find particle system file 'particle_imp_dirt.ps'

Full hpl.log attached.
