For the last hour, i was wondering why latex could not see my figure file during compilation.. Finally, i figured out that latex working envirenment (where the _temp.pdf is produced during compilation) is not the directory of my current .tex file.. WinEdt/Miktex treated as if all my .tex documents i edited so far, belong to the same project, and assigned the first .tex file (which is under a different directory) as the main file of the project..
In order to correct this, i modified the Main File attribute via Project Manager window in WinEdt/Miktex accordingly.
