Updated my phone to WP8.1 now i can't run my games

Hi, i’ve updated my phone to Windows Phone 8.1 and now i can’t run any game i"ve made (i release them as development build)
Meanwhile I have a games that’s running on unity and it’s from the store and it still running fine.
Please help me I need this in a couple of days.

Hi,

which Unity version are your games made with?

I’m using Unity 4.3.1.

Could you describe what happens when you’re trying to run your game?

The powered by unity logo appears, then the game is shut down (and ofc it brings me the main menu of the phone).

Did you try running it with VS attached to see where it crashes?

Nope, I didn’t I have limited time.
But I’ll do as soon as possible.
But I’ll tell you if there is any news.

Thanks.

Well here is the thing, I guess it’s a problem of licence, that’s it. (since i didn’t install it from the store so it has no licence.)
I had worries because i have many apps including ones made by unity and downloaded from the store and they all worked just fine.
All I had is to redeploy the game one more time on the phone with the new update, now I feel a little stupid.
Thank you for your time Tautvydas.

No problem :).
