st: my probit does not converge in Stata 11

[Carl-Magnus <callebjuggren@gmail.com>]

Dear all,

I have recently switched from Stata 10 to Stata 11 and discovered that I
cannot get my probit to work in this version. It starts to iterate and after
about five iterations it says (backed up), and then it gets stuck on the
same log psuedolikelihood, forever it appears. I use the exact same commands
as I did in Stata 10, and in Stata 10 it only iterates a few times before it
gives me the results. 

Originally my command was of the form xi: probit ….. but I have also tried
just probit and other simplifications and it still does not converge. I
noticed that some previous threads also concerned this matter, but I did not
find a solution to the problem anywhere.  If anyone could help me with this
I would be very grateful. 

Best regards
Carl Magnus Bjuggren
