Anyone else having survey issues? For the past 24 hours or so every survey that I click on returns the message "request expired." Logging out and logging back in does not fix the problem. Everything else, like my survey history and reward history, is working fine, I just can't attempt any surveys. Have written their help desk, waiting to see what they say.
EDITED TO ADD: Never mind, looks like I had some corrupted cookies, deleting all of them seems to have cleared up the problem.
