Titanfall icon disappeared "My game" list

Good evening. 

Since this evening i'm facing problem with the software. I bought it last week and played fine until now with no problem. I noticed that the game icon from "My game" has gone and i tryed to click on the "Refresh" button to make it appear again but with no succes. Its like Origins doesn't recognize i bought the game.

I tryed to insert again the CDkey but of course the system tell me the CDKey is already in use. I tryed to re-install origin but again I cant see the game icon. I tryed also to delete the Cache folder of the game and re-downloaded it but it doesn't work, i can't add it to the game list. If i try to do it manually, somehow i can launch the game but i can't play with it becouse it take an age to load every game. The real problem is, i need to make it appear on the "My game" list becouse if i lose the .exe that is on my PC, how am I going to play again if I lose the .exe? Sorry for bad english.

Hope someone can help me, have a good evening guys.
