C# can't add MediaPlayer object, get the following error
<p>I am working on a project which needs to play a video on the screen. I created a form, dragged and dropped COM Component called Windows Media Player, customized buttons, OpenFileDialog, size etc. The object's name was let's say "axWindowsMediaPlayer1". I can control things, with methods like "axWindowsMediaPlayer1.play", "~.stop", "~.fullscreen = true" etc. </p>

<p>But today I just opened my project, and in form screen there was no drag&amp;drop MediaPlayer element. But anyways, while running the program, the video was being shown, but there were no object named "axWindowsMediaPlayer1", on the form screen.</p>

<p>Then I tried to drag&amp;drop another Media Player element, just to make sure there exists an "object". But I got the following <a href="http://i.stack.imgur.com/d2RYq.png" rel="nofollow">error</a>.</p>

<p>I deleted everything in the Vide form now (both the design and code of the form), created a new form to do the same thing, in order to try some new methods, but now I can't even add this component to my form.</p>

<p>Can someone help me?</p>
