First, this topic should probably be in Tech Support.
Second, welcome.
Ask Sonny_Ressetti about his replicas.
To download components, go to our "Components" link on the home page. Then, click on whichever component you want to download. Once it is done downloading, open up that folder. Then right-click on your Robot Arena 2 shortcut. Click "Properties" then "Find Target". Click on the Components folder inside your RA2 game. Now, go back to the folder with the stuff you downloaded in it and copy all of it over. Now, start your game and they should be there.
Hope I could help. :D
