1) Register at Gamersgate if not already a member http://www.gamersgate.com
2) The game you want to purchase is Paraworld http://www.gamersgate.co.uk/DD-PW/paraworld
3) Once the game has been purchased, download the installer, then double click on the installer to start download of the game
4) Do something else whilst it downloads
5) After the game has finished downloading the installer will run, Install the game.
(note that it is recommended to install to a different folder then C:\Program files as sometimes this causes problems for the boosterpack and seasmod installation)
6) Download the Boosterpack, Map pack and Seasmod if required but do not install them yet!! (if you install the boosterpack it overwrites the main .exe files that are modified to remove TAGES and cd check)
7) Find the directory that you installed Paraworld, go to the bin folder and select PWConnect.exe, PWClient.exe and Paraworld.exe and make a copy of them on the desktop

9) copy back the 3 exe files from earlier, overwriting the ones from the boosterpack
10) Play the game
