bryce, yea, there is a fixed issue.
but include works fine in 4.50 too.
the fixed issue (iirc) was about person including same script all over again.

anyways, this error seems that this is not the case here.
this error clearly says that his messenger.kix and this kixtart.kix form a loop that infinetely go on.
