help urgent! website down, wp supercache

Hello,
I just installed wp super cache, and because as soon as I turned it on I realized I should have fixed first some design details first so the stored pages on the cache will be as I want. I turned supercache off, and I was fixing the design, but suddenly I can’t see anymore either the website or the wp-admin to edit themes. Please help me to fix this… 🙁
