All I can see is the little sliver in the bottom of your screenshot, but I think I see bin64 and Gw2-64.exe on your desktop. You don't generally want your game's data files just sitting out on your desktop like that.
I would recommend putting Gw2-64.exe, Gw2.dat (if you manage to get any of it downloaded first), and bin64 into a new folder called "Guild Wars 2," and putting that on your C:\ drive or whatever drive you prefer to keep your games on. So it is located in C:\Guild Wars 2 or C:\Games\Guild Wars 2. You can then right-click Gw2-64.exe and go to Send To... Desktop to create a shortcut if you want it.
As far as the downloading issue, Quaker's pretty much got it covered. In my experience, that problem is almost always related to an anti-virus or firewall interfering with the download.
Well, there was a sizable patch on Tuesday, so you should have had a download for that. I noticed the patch took a little longer than most, but by that I mean 5-6 minutes for me. No idea why the patch took so long for you.
It follows the lore—though it may not follow the lore that you (or sometimes I) would prefer.
Well indeed he could mb scratch the SSD, buy it later and for now gp with HDD and 960/760 or HD7950
Those are fine choices, but note that the HD 7950 is the oldest card from that price point based on that silicon. It was re-released as the R9 280, and then was replaced at the same price by the R9 285 and most recently the R9 380. I'd recommend the R9 380 if buying an AMD card at this price now unless you can get a significantly better deal on one of the older versions.
Everything is compatible and it's a decent build. A 600 Watt power supply is more than is truly necessary for this build, and you could safely go with a 500-550 Watt unit instead, if one is available. EVGA is a good power supply manufacturer.
The GTX 750 Ti is enough to get you good performance in Guild Wars 2, though you may find that a 750 Ti sorta scowns by in some newer games at 1080p. If I had any input there I'd say that a faster video card may be more important than having an SSD, if you plan to play more than just GW2. An SSD is a fairly easy upgrade later on. The GTX 950 is only about $20 more expensive than most GTX 750 Ti's, is a considerably more capable card.
