First off, you need to be on the hamachi network, which is PowerUP.. PowerUP2 or PowerUP3 and remember it's case sensitive. The password to all of those is 123.
Here is the download from Hamachi: https://secure.logmein.com/US/products/hamachi2/licensing.aspx
Be sure to select the free version. Remember, we are only using Hamachi until someone is willing to donate to pay for a dedicated server, so we don't have to use Hamachi.
How to connect to Hamachi:
After installation, open up hamachi, and it should prompt you to connect to a network. If it doesn't, press the power button, and then click 'Network' ---> 'Join an existing network'.
If you need v62, go to our temporary website, http://powerupnow.webs.com/, and on the left side bar, click 'Links' and then click 'Entire v62 Folder'. It comes with everything you need.
However, if you already have a CLEAN v62, that was never used for any other server, you can just select 'PowerUP Full Client', which comes with the client, and all the custom files you need for PowerUP.
Once downloads are done, you will need WinRar. You might already have WinRar, so ti find out, just right click on the stack of books you just downloaded, and you should see a selection of options for 'Extract'.
If you don't have WinRar, then you can download it from http://www.rarlab.com/. You can find the download but scrolling down and selecting whichever language you want, 32-bit. Here is an example for English users.
After all that is done, right click on your desktop and select 'New Folder'. It would be best to name it 'PowerUP MS'. Then right click on the stack of books that you downloaded, and click 'Extract files...'. A window should show up. Select the folder named 'PowerUP MS', or whatever you named the new folder. Then an extraction process should begin.
When you have done everything above, open Hamachi again, and double click on '[Owner]Smim'. A black window with a bunch of numbers should come up. You can minimize that. Then go into the 'PowerUP MS' folder, (the one you extracted too) and double click 'PowerUP'.
And now you should be in game. :D Have fun.~
