Hi, I recently got a new Macbook Air. I had everything backed up from my old Macbook but in fact, there wasn't much so I just went ahead and did a clean install. Everything's dandy except for one thing; I can in no way install Skype. I drag it into applications, initiate the installation...then get to 'Accept License Agreement', click 'Accept' and the icon just fades out of the dock. Restarts, copying it across from my backup drive's applications folder, nothing is of any use... Anyone come across a problem like this?
