Game REDOWNLOADS on EVERY launch.

So I recently (2 days ago) started playing Guild Wars 2. Played it for a bit and then got off. Yesterday, I wanted to play again. But when launching the game it started redownloading the entire 70GB again. After that I got off and came back a couple of hours later to play again. Guess what, it started redownloading the 70GB again.

It's pretty frustrating, even after 2 times of needing to go through this.

Is there a fix to this? My thought was maybe get it on steam?

If any of you guys have had this problem, I would really appreciate the help! Thanks!
