Sorry to be a pest but this happened on my ED as well:
00:42 XenoBot: Loaded settings successfully.
00:45 XenoScript Error:
Script: [60+ M] Port Hope Water Elementals.xblua
Line #: 3340
Chunk: [string "C:\Users\Adam\DOCUME~1\XenoBot\Scripts\\_60.. ."]
Error: bad argument #1 to 'pairs' (table expected, got nil)
This is an error with user-input and should not be reported as a bug with XenoBot.
