LMFAO ok so it was just avast anti virus scanning everything as it was being extracted that was slowing it down to a crawlso, i guess i'm just stuck with this strange situation
i've just been restarting the extraction repeatedly once it gets too slow... so at this rate it'll be done in like a week
disabled it and it finished extracting in like one minute xD
i wish i'd thought to try that sooner, would have saved me HOURS, but at least now i can play !
