Anyways, I am here to ask for some help from the community, or anyone who knows about this issue.
The former issue:
After I formatted my pc, I wanted to install WoL and HotS again, to play it. The first time I installed HotS it did only download 2gb worth of updates. Which is cool, I can deal with that, but the issue is here. After a looooooong while, I formatted my pc again, and after installing WoL and trying to install HotS, I realized it doesn't read the disc from Hots no more (I am 70% sure it did the first time after formatting) and no, I don't mean as in the disc is damaged it doesn't read it anymore, the disc is as new. What I mean is that it doesn't even attempt to install any files from it, it directly wants me to download the whole HotS again.
It's not the regular 2gb I had to download after installing it, and yes I am aware there were update patches, but none of them adds up 7 gb. Is there some step I am kinda forgetting to do because of a momentum of retardedness that I am going trough, or did something change?
