endogenous switching regression model

[Corine Ngomi]

Hello,
Please I am new in stata so it's quite difficult for me to solve some regression problems.

Actually, I am trying to estimate an endogenous switching regression model using the movestay command where my selection dependent variable is ADOPT(dummy) while my outcome dependent variable is HDDS(continuous).
Unfortunately I keep getting the following error. i tried to add the variables progressively but either of the messages below. the strange part is that the same command was ran on a different computer using the same of stata and it produced results without any errors.
I am getting desperate. Can someone help me solve this problem? Please

Fitting initial values .....

could not find feasible values
