title: Cannot open an existing project in Netbeans
body: <p>I'm using Netbeans 7.0.1 in my computer, I've already created several projects in that same machine, then after installing/adding plugins for Android, I could not open any project in that same machine. How do I make my netbeans open my existing projects again? Do you think the installation./addition of plugins has something to do with the matter? Do I need to remove all the changes that I made? How?</p>
  
  <p>And I forgot to mention, Whenever I try to "Open Project" it will show a window which displays the location of the projects, this gives me the idea to go to "My documents\NetBeansProject\ProjectName", however, when I click the project that I want (e.g GenReport) in the textbox (the label is Titled 'Project Name' ), this is shown --</p>

    <p>unrecognized project;missing plug-in?</p>
