The user whose post you attached to was not using Skype, so I started a new topic for you.
Audacity 2.0 is obsolete. I suggest you get the latest 2.0.5 from here: Audacity ® | Download for Windows .
The easy answer is not to use Audacity to record Skype. Audacity is not intended to record Skype. At best you will get yourself and the other party mixed together and one party may be louder than the other.

When you do record with Audacity, turn Skype off, and you will probably want to turn off sound “enhancements”:
Audacity Manual .
If you still get dropouts, shut down more programs before recording. See:
Missing features - Audacity Support .
