First off I want to point towards searching the forums first before actually posting any questions. Now if you did search and found nothing, then great, but if you didn't do that at all.
Then I suggest doing that next time.
Aside from that, just to answer your question quickly. You can only add teams to the game by taking teams off. Which means if you want to add Greece or whatever national team you like to use, then you'll have to remove USA, Russia, or someone first.
That's the only way to make the game function afterwards and you also have to make sure that if you get rid of a team in a certain division or anything like that in whatever order. Then you must place the new team in that exact division, because the game is hard coded to respond a certain way with certain situations. If you take a team out of a division, conference, or whatever. Then place a new team in not the same area and in the opposite, you'll see that the game just won't start.
I know this cause I have been doing some stuff lately with some leagues. The CHL has lost a few teams over the past year and gained a few as well. Which means I would like to add them and so forth, but it's hard to get it all to work.
But then again, practice makes perfect or whatever it is that they say these days.
Anyway, to make a big long story short. Welcome to the forums, please search before posting ahead of time, and ultimately I hope that I answered your question right.
If not, there are plenty others around here that can correct me or set things right.
