I tried to duplicate my project, but there was not enough space on the hard disc. so I cleaned up some unnecessary files and duplicated the project. But while I am trying to open the project error message appears on the screen. "[Resource not found:"Resource/download.php"]

it is interesting that it is possible to open same project on another pc . I realised that it is not working specialy on my primary pc. So I tought that I ceaned some necessary files of x5 by mistake.

I tried things below to fix problem;

I uninstaled x5 and all other compnents from pc and loaded again, but it is still not working.
