Hello!
Welcome to Linux Lite.
Sounds like what happened is that when you tried to install Skype from Microsoft's website, something needed to run it - called a dependency - didn't get installed first, resulting in a 'broken' package. This happens frequently when dealing with non-LL (non-Ubuntu) sources, which is why it's recommended to install software either through the Lite Software Center or Synaptic Package Manager.
Here's the fix:
At the main screen, click Menu > System > Install/Remove Software. A prompt will appear that asks you to input your root password. Once you do, Synaptic Package Manager starts.
In Synaptic, select 'Edit', then scroll down to and select 'Fix Broken Packages'. If there are any, it will 'fix' them, then tell you it 'Successfully fixed dependency problems' in the status bar at the bottom of the Synaptic screen.
You can then enter 'skype' in the 'Quick filter' box at the top of the Synaptic screen. This will take you to where you can click on 'Skype' and select 'Mark for installation'.
For ME, this installed Skype plus all needed dependencies and creates a 'Skype' entry in the 'Internet' section of the 'Menu'. It should for you, also. If not, say so, and we'll go from there.
You shouldn't need to edit your /etc/apt/sources.list file unless you somehow added some kind of third-party repository, but this can also be done in Synaptic (Settings > Repositories > Other Software), or in a terminal with sudo nano /etc/apt/sources.list or sudo leafpad /etc/apt/sources.list. Speaking from personal experience, unless someone knows exactly what they're doing, editing configuration or other system files manually can break an install so badly that it may need to be installed again from scratch to fix it.
Hope this helps...

A gun in your hand is worth more than a whole police force on the phone.
