Solved How Do I Install Team Fortress In The Orange Box?

[sjc1138]

I already have the free version of Team Fortress 2, and I'm now purchasing the Orange Box. What will happen when I try and install it? For buying it I wanted some of the premium features such as unlimited trading and extra backpack slots. Will I have to reinstall? Thanks

Solved this myself! For all those who wish to upgrade to TF2 full from the free version, first, uninstall the free version. Then install Orange Box and leave it to update for a while. As long as you are using the same Steam account, it should let you start the game with all of the premium features (New hat, unlimited trading.)
