Guild Wars 2

I was looking on GW2W and this was said about the music for Swamp Fractal: The music track is a hidden track from Guild Wars Prophecies. This could be also heard in The Catacombs.
Here’s the wiki link: http://wiki.guildwars2.com/wiki/Swampland_Fractal
I really really really want to be able to listen to that hidden track..it’s so beautiful. Now i just try and spam fractals just to hear itxD

It’s such a lovely song, been looking for it for ages!if someone knows or can find out what the name is I’d be very grateful also!

Quite commonly (probably twice an hour) my game crashes and i get a box with a message:
‘A serious error has occurred that prevents the program from continuing to run. You can help us prevent this error from occurring in the future by reporting it to ArenaNet. Please press the Send button to report this error.’
underneath this are three options- ‘Show details>>’ which if you click says :—> Crash <—
Fatal Error: Fatal disk-error (23) on read,
App: Gw2.exe

it also gives details about my system which i wont post due to privacy.
the next option to click is: ‘Send error report’
and the final option is: ‘Dont send’
In addition, when i next load Gw2 a box also appears saying: ‘Last time Guild Wars 2 ran, it detected a problem in its game-data. We recommend that you let the game verify and repair its data. Would you like to do this?’ ’ Yes’ (option) ‘No’ (option)

If i click ‘Yes’ to repair and verify the game will start to ‘Verify Archive…’, meaning it is scanning my gw2 files..BUT at around 17,000 files remaining it crashes and the first error report comes up AND when i load up Gw2 the same Last time Guild Wars 2 ran, it detected a problem in its game-data. We recommend that you let the game verify and repair its data. Would you like to do this?’ appears….

This is affecting my gameplay in PvP, dungeons etc.
I find that it most commonly occurs when loading a new area, whether it be wp to a new zone or changing PvP map.

It’s been happening for months, is there something i should do to solve it?
