Please ignore that warning. The LAM-BIAS option has now been used
successfully for many years and, at least for what concerns inelastic
interaction biasing, it can be considered as very well tested.
(Perhaps other features have been less tested, in particular
decay direction biasing, which has been introduced only 
in recent times). 
I will try to have that message removed or modified in the next
version
