Although you thank us for our comments, you don't really address any of them! 

I can't see any Stata programs here, just a do file with references to other do files. Sorry, but this is not a problem report that can be commented on as it is really is not clear what the problem is. The detail here does not add to "doesn't run properly". 

A problem report would be a comparison of the _same_ code on the _same_ data in _different_ versions of Stata showing that the _results_ differ. That and only that would support your assertion implicit here that changes in Stata have caused problems. 

I think the best way forward for you is to take this up with Stata tech support. They are going to need to see a lot more information, minimally two logs gained as above showing different outcomes. 

I echo Neil's separate bemusement on what is meant by "portable" and "fully installed" here.

Many thanks for your helpful comments. I run the program in the
portable Stata version 9 and 10, and it run well. However, the program
doesn't run properly in the Stata 10 which is fully installed into our
computer. I would appreciate if you could help me find out whta might
go on here:

 For your reference, I am enclosing the codes here:
