EAs installation issue

 
I was using MT4 plateforme till january 2014 and I restart a few days ago. Before my break I could install any EA by placing the file in the expert folder of my MT4 plateform, but now the new EA I'm trying to place in it doesn't appear in the plateform in the EA contain but sometime in the indicator contains . I realized that there's a little change : the expert extained before EA files with a "4" now there's a "5" instead (see the picture I joined), is there a relation with the issue? I don't understand what it's happening, could you help me?
