Vishal,
copying the Main into another folder and loading it from there, you will most often have the issue you are observing: The SubVI is not found.
This happens, because LV just saves the relative path to the sub if possible. So if you copy the subvi as well into the new folder, everything will work fine for you again.
But please note that, if a vi of the same name is already in memory, LV will use this vi instead of the one you (maybe) want to have....
hope this helps,
Norbert
