is it normal to have 9 Gb free and not to be able to have enough space for this patch ? i mean wow is crappie video game and still the most resource demanding? i'll stop paying it rather than buy another hard just to play it.
The patch its self is small but the way blizzard does the updates you have to have enough room free on you HHD for the whole game. If you have the PTR i would suggest deleting it then reinstalling after the patch or deleting any file you can easily get back after you patch.
