I have a Macbook Pro, and Skype always worked just fine on it. The other day I instant messaged my friend and never heard back from her for a few days. Earlier today, I happened to log into Skype on a different computer (a PC of course) and suddenly I had a message that she had sent back to me the day after I had originally messaged her! So, I logged back into Skype on my Mac and it still does not show that I have received anything from her, but it will show it on my PC. I have logged in and out, I've restarted my computer, I've attempted to uninstall and reinstall Skype on my Mac (although that seems to be a riddle in and of itself anyway). Needless to say, I paid enough money for this Mac, and I'm VERY frustrated that it has given me SO many problems! Can anyone help me?
