Samsung Apps On Samsung Kies Wont Suppost My Samsung Galaxy S (gt-19000)?

I bought my Galaxy S phone about 4 days ago and went through the manual a bit and I do have a sorta clear idea in what i do with it. But when i plug my phone into my PC, it connects fine with “Samsung Kies” and comes up in the corner with the GT-19000 (which is the phone) so i know its connected, but when i go to download apps from Samsung Apps, it says that my Galaxy S isnt supported by Samsung Apps, yet the whole entire program came with my phone. Anyone have a clue why it wont connec with that pne part of the program? Any answers would be a great help. Thanks
