NONMEM execution problem

Hello all, I am having problem with NONMEM 7.2 execution. I am not sure about the problem as it was working fine until recently. Could you please suggest any solution? Here is what I see when I run nm72 example: --------------------------- C:\Users\bajajg\Desktop\NONMEM run test>nmfe72 example1.ctl example1.out doing nmtran WARNINGS AND ERRORS (IF ANY) FOR PROBLEM 1 (WARNING 2) NM-TRAN INFERS THAT THE DATA ARE POPULATION.
