Skype

I am having some Skype issuses. I got a microphone, but Skype was installed on my old computer. I had to replace that computer. We still have it to do basic internet searches and I was planning on using it for Skype but the microphone won't work on it. I tried to upload Skype to the new computer, but I would lose all my contacts and my username. My husband thinks he has a solution and hopefully the microphone will be up and running tomorrow.
