LR CS6 update failed - can't use LR anymore

Hi all,

I just wanted to update my LR CS6, but for some reason the update failed. I wanted to restart the update as well as LR, but I can't open it anymore. LR says: "There has been a problem trying to opening LR". I wanted to re-download LR from my account, but the Adobe website says there has been a problem loading my downloads. Can someone please help me? It's useless now and I really need LR today.

Thank you.
