Rest Mockservice not working after a SoapUI restart

I have created a rest mockservice and triggered the mock from command line using mockservicerunner.bat. It works for the first few times. After restarting the SoapUI, this mockservice isn't working from both the command line and UI mode. The mockservice gets started but it is not actually responding me with the data which it is supposed to do. When I create a new mockservice, which is an exact replica of the not working mockservice, then this new mockservice works and responds with the correct data. Any pointers why thisn't working? Also please let me know the solution ot fix this issue.
