I believe it is different for Windows 8, so again, Google. You can also hold the Windows key and press 'R'. To do this you can open the start menu, type 'run' without quotation marks, and hit enter. How to open the Task Manager (not trying to be condescending, it's just in case a rookie needs it) Open the Processes tab and close anything that has to do with Hamachi. To be sure that it is closed, open Windows Task Manager. Right click the Hamachi Icon and Exit Hamachi.
In your windows toolbar, click the upwards-pointing arrow to 'show hidden icons,' also called the 'system tray.'
I strongly recommend that you try this, Jason-Alaska, since our cases seem to be more or less identical. Now that all three are done, I can play Blacklist multiplayer. There are three things you have to do, while I had only done two. I've seen that other people have issues with Hamachi and Blacklist and so I had disabled Hamachi, which originally didn't work, but it can easily be a tad more complex to do than you'd think. This is even more likely to be true, due to the fact that I could never play Conviction back in the day, even though I didn't have what caused Blacklist to malfunction: Hamachi. Keep in mind that, when I tell you what I did just recently to get it to work, I had already done everything else as well, so there is a good chance it might've been the a combined result.
