Logged out while teleporting or crossing sim

For about 2 days, i have been unable to teleport, or cross a sim. as it goes thru "sending thru destination", it logs me out everytime. this has been happening since the update. i even disabled the windows xp firewall, and it still happens. i have knology broadband internet, wondering if that has something to do with it? i have not found anything on the forums about this. can anybody help me?

after 4 hours, i finally figured it out. it turns out the time and date was messed up on my pc. so if anyone else has probs teleporting or crossing sims and getting logged out, CHECK YOUR TIME AND DATE. make sure it is right.
