Hello knro,
Problem is solved after max told me to make a small change in the kstarsrc,by adding -origin to solve-field in line 58.Thanks for your help anyway.

Max was trying to combine Kstars with SkySafari to allow easy framing,so he wrote a program to utilize the solve function.However,the program will report a failure if the skysafari skyset is not uploaded,even if the user is not using SySafari.That's why I was having a problem at the very last step.
Since I am not using SkySafari,I just changed the kstarsrc instead.
