I'm trying to get settings back to my pc since yesterday and this is my problem : when i want to open search window i'm getting an error like this : " File needed to start search companion not found . you may run setup ( what setup ?? ) . And when i'm connected to internet works fine . I must say that yesterday when i was connected i was searching for somebody in my local network and my pc stopped responding and i restarted then , since then i receive that error and when i'm online works fine . Not system restore is the solution . A setting has changed and must be undo' . Thank's for all your contribution .
