I started playing Foldit Friday 4/20/12. I set up an account and did the Tutorial Puzzles. I even tried some of the Science Puzzles. Things seemed to be working fine. Then something changed and I started getting the error "couldn't connect to server: Error contacting server." What can I do to make Foldit work again? Does Foldit's server go down Fri night or Sat for maintenance? I keep looking for helpful tips in the wiki and such but haven't found the answer yet. Please help if you know what to do. Thanks!
