Rolled a new character, LICH starts and works fine except for Infomon - only for this character?

;infomon
--- Lich: infomon active.
--- Lich: error: undefined class/module Scripting::Hash
C:/GS/lich/lich.rbw:2209:in `load'
C:/GS/lich/lich.rbw:2209:in `block (2 levels) in <module:Settings>'
--- Lich: infomon has exited.

I am running windows 7. I shut everything down, rebooted, re-downloaded LICH install files from website, copied over the existing ones, no change.

All my other characters work fine - same account and other accounts.

Any help appreciated. Thanks.
