um make sure all your files are not read only. and dont ignore, as if it does not update the files, which it was not doing because you were ignoring, then you cant play.
also i made the changes to this, and yeah faster kinda, when its syncin the files it takes quite a while. and it probably shouldnt. now while my computer is not the latest, its still 2ghz. and should not take as long as it is.
although ill leave it going, my mate started it at the same time as me and is on 35%. and im at 5% which is not cool.
but yeah must be a problem at my end.
