After updating the Adobe Flash Player, Shock wave Player and Apple Quick Time Player to latest version I got this problem. Whenever I visit the trailer website I am getting a faded question mark in Quicktime Logo in the browser. When checked with Apple Quicktime support team, they asked me to re-install my player to stand alone player. I did that also still cannot able to solve the problem.
How to solve this problem?
As usual I googled for the solution I cant find it. Then went to search in Yahoo and got the solution for it. To fix it in firefox find out the file name NPSWF32.dll.
Normally it will in C:\WINDOWS\SYSTEM32\Macromed\Flash\NPSWF32.dll. Copy this file and paste it in C:\Program Files\Mozilla Firefox\plugins folder. Now it will work in Firefox. Copy the same file in C:\Program Files\Internet Explorer\plugins folder. This one will solve the problem.
