Guild Wars 2

Hey peeps,

Basically my issue is that I recently got back into playing GW2 and when I tried to load up the game today, it’s attempting to download itself all over again. Now I haven’t changed anything with my game, least of all uninstall it and when I go into the Guild Wars 2 folder in C: on My Computer, it shows a 17 mil KB size gw2.dat file.
My computer shows no signs of it being uninstalled and the only thing I can think of is that I ran CCleaner today which cleans up a lot of useless crap on my system such as cookies and internet history and that might have changed something on my PC which causes the client to not recognize the game as already being on my system.

Any and all help is greatly appreciated

Update – I’ve run the “repair” tool for GW2 and it only checks through the amount of files I have already downloaded onto my system since discovering this problem. It would also appear that the game is not appearing on my system twice, it just seems to have lost all of the data from yesterday evening until today.
I’m not entirely bothered by this since the download will only take about an hour but it just confused the heck out of me.

Update – OK this will be the 3rd time in a week that I have had to download the entire game from scratch and I really have no idea what is causing this. Originally I thought it was an anti-spyware program I had running but it has happened again after removing this program from my PC

Are you running the game as an administrator? If the game cannot read/write to the file, it will attempt to download it again.
