Oh, do I need an extra track pack?

What I did was after the fresh install of GTR2, I followed the install instruction of the GPC79 v2.5 which was to copy the files to the relevant directories. Should it be supposed to be able to run right away?

I checked the tracks(the originals come with the install package) are all there, does the championship automatically select the correct track to load?

On the other hand, can I select manually a track for the championship to begin with (I am newbie for this mod

)?
Anyway, if this is the case, where can I get the trackpack that can run this baby? Would you show me the link? Thx a lot for your kind attention!!
