i can open client but nothing shows up but sound is up

My client was corrupted yesterday and it updated itself automatically. However, when i open it again, nothing shows up but i could hear the sound of client and i also can click the buttons which are invisable. So i uninstall it for few times, changing installing address, which didn't help. And after few reinstallings, i could't even see my client when i log in, my client became invisable too XDDDDD. And the thing is taht i can hear the background sound when client is up, and i can click the bottons which are invisable like after logging in.
