im exploring the TR1 map and getting a

'sound not executable molecrab moan' continue yes/no..

but the molecrab file wav is in the sounds folder in data files... what do I do?

Looks like you didn't register the BSA properly.
Read the ReadMe document that comes with the mod for instructions.

Actually the sounds are NEVER in the .bsa - so this is not the case ;P

Although I can't think of a reason for this bug...

Are you using the map 1 file that came bundled with our map 2 release?

its ok, I think because I copy and pasted the two folders inside the sound folder rather than just the sound folder itself.

Im gonna do a complete reinstall of MW... If I d/l map 2 I dont need to worry at all about map 1 right? the landmass is included in 2?

Correct. Map2 has the updated Map1.
