so i downloaded a pirated version of minecraft a while ago, loved it, decided i wanted to buy the game, went to minecraft.net and kept getting the oops error, read on a major minecraft forum that the problem was that the pirated version, which i thought i got rid of, was keeping him from accessing the website. From what ive gathered i think im supposed to go to C:\windows\system32\drivers\etc\host so i did that, apparently im supposed to access the code in notebook and then delete it and save and then everything should be fixed, well, i did that, clicked save, and then a message popped up saying this "C:\Windows\System32\drivers\etc\host.txt
You dont have permission to save in this location
Contact the administrator to obtain permission
Would you like to save in the My Documents folder instead?
YES or NO" and it doesnt do anything, if someone could help me it would be greatly appreciated, because i have absolutely no idea what im doing.
