I don't pay too much on spelling myself, but geez, try and buy a dictionary (No offence)
After installing the initial game, your game pretty much downloads every update over the past 2 years when first starting up. Then the first time you load a map, to download an initial 3000-4000 files. (Mainly graphics, I gues).
And then in the beginning about 100 files every time you visit a new area. Guild Wars also runs "hidden" downloads in the background. As far as I know, there is no way to stop them...
As for slow internet, welcome to 2008
SO summed up:
Insalling all the bs, Download all the update + files, you will probably be sitting at your computer for an hour/2 hours downloading (Depends HOW slow your connection is, I pray to god it's faster than 100kb/s, for you anyways).
