No worries. You don't need to uninstall anything.
Log into your Logmein account from your 2nd computer. Because you want to work on the main computer using the 2nd computer.
When you log in, logmein should direct you to your computer list. Which will only have the one computer, (main computer).
And the main computer name is in blue. It is clickable. So click the main computer name.
Another window opens up and asks for the password for accessing that computer. After you enter in the password, you'll be directed to a screen which gives you the available features for the account you have. You will want the "Remote access" tab. Click that button and you will be able to see your main computer and work on it just like you are sitting in front of it. It is the coolest thing!
Does that help?
