Bringing up this old topic, but I have the same issue. Though my file is spelt correctly (unlike the first post). Error message:
ERROR locating resource for 'CHAIN3'
Resource [BVICON.DLG] not found in KEY file:
[./chitin.key]
ERROR: preprocessing APPEND_EARLY [darian/dialogue/bt1dar.d]: Failure("resource [BVICON.DLG] not found for 'CHAIN3'")
Stopping installation because of error.
