Trouble updating most recent version AND need API Key change -sincerely, new guy

Hi...MAC user and setting up bot for the first time after buying from a friend.

Thank you in advance for your patience. I feel like I've looked all over and I'm having trouble figuring out how to solve this problem.

1. I installed an older version of the bot and am getting an error telling me so when I go to run it. I downloaded the most recent version and when I install it the same way as the previous version, I get the following error -

events.js:182
      throw er; // Unhandled 'error' event
      ^

I can't seem to figure out how to get the most recent version of the bot to run on my computer. There's a VERY good chance that it's something very simple but any suggestions are appreciated.

2. I just got the bot from a friend. I need to update the API Key. From what I understand, the newest version of the bot will allow me to do this on my own. Am I correct in that assumption? If not, are there steps I need to take in order to make that happen?

Thank you again. I appreciate your patience as I dive into this all.

1. for the error, something is already occupying port 5000, which needs to be clear for gunbot.
2. you can't just get the bot from a friend. there are procedures to be made for changing ownership. firstly, the original ownership needs to get validated from Gunthar, then a certain procedure using escrow needs to be done for changing ownership, during which your keys are validated. this happens on gunbot's servers, there's no way around.

Thanks for your help. I cleared the port and updated the bot an am starting the process of changing ownership. Much appreciated.
