TNMIN from mpfit library [message #90215]

I'm using TNMIN to minimize a very complicated function, which for reasons I cannot use MPFIT. Everything seems to be running smoothly, but after a handful of iterations it gives me

status=-18
errmsg="ERROR: Line search failed to converge"

While I understand what that means, I'm not sure how to massage the inputs to TNMIN to get passed this error (or perhaps this isn't a true error but rather just another stopping condition?). Does anyone have any advice? Craig, are you out there?

Thanks gang,
Russell
