Quick Question about the Download

Hey guys,
I have a quick question and i am sure that you fine gentlemen and ladies can help me out. How much bigger is the Full Version download than the demo version of Democracy 2?
I am on an unstable dial-up connection and in order to download anything bigger than 1mb i have to go to the local library and download whatever i might need onto a flash drive and then transfer them to my home computer. This is what i did with the Demo version of D2 but now id like to buy the thing & do not know if i need to go back to the library or is the download for the Full Version just a key that i can get thru this awful connection. Thanks so much for your time.
Joe

The full download is about the same size as the demo, but you do need to download the whole thing again as a separate file.
