Thanks everyone. You really helped...I've never done this before and was quite confused. However, I've tried all of your suggestions and downloaded all new software updades and . . . they work!!!! I don't know which one worked, but it's working! I now have SKYPE. Thank you all for your...
Skype suddenly would not open, so I downloaded it again and got the message "No mountable file systems." Now any file with dmg won't open. How do I fix this???
