Hi. I'm not sure if this is the right forum for this thread, so apologies if it isn't. I have an Acer Aspire One Laptop, which I bought just before last Christmas. It runs Linux. I haven't had a problem with the messenger service before, but fairly recently (a couple of weeks ago), every time I logged on, it told me that 'The Certificate Chain is invalid'. It took ages to load, and eventually did so, however, the nudge button was greyed out, and people couldn't receive my animations, although I could see them working as usual on my screen. After reading some other forums, I installed live updates, which seems to have fixed the 'Invalid Certificate Chain' thing, but nudges and animations still don't seem to be working. If anyone has any ideas of how to fix this as it is very annoying, I would be most grateful. Thanks very much, Amy
