yshout not working at all.......

Hello Everybody,
I have uploaded the yshout folder in modules/ folder as is guided..... then I have activated the yshout module from admin/modules/ ........ but now I am getting some errors which states that they are not able to find some functions in drupal (menu_execute_active_handler,drupal_add_js...). I have searched these files (menu.inc, common.inc...)and have replaced with the corresponding one. But still getting some problems as system is searching for those functions which are missed in new replaced files and were there in the old one's.
Suggest..................
Thanx in Adv...........
