A Skype for Mac w/ Video post that I reported earlier this morning is an unstable build and may delete your contacts and other data. DO NOT DOWNLOAD it. I apologize and only a minute ago was recently made aware of the problem. A Skype developer let it be known that it was a previous unstable build and SHOULD NOT be downloaded.
I apologize for posting about it before but I was not aware of the problem until a minute ago. If you have downloaded it then just uninstall it and install the latest Mac version from Skype.com. I uninstalled the unstable build on my MacBook Pro and installed the official Skype for Mac and everything was a-ok.
