I need some help, and I can't find anything online that can help me. It all started when I popped in my Diablo II: Lord of Destruction disc to start playing. For some reason, the window "please insert disc" comes up, and I don't know what's going on, so I search up the internet and find that with a latest patch (which I know I have), I just need to get a file off of the Diablo II expansion disc and I can play without the disc ever again. So I go do that, only my computer now won't even let me copy the one file I need because of some "I/O" error. What the hell is going on?! The drive itself isn't malfunctioning, since I've already tried running Warcraft III and a few other games and had success, but why is it being such a pain in the ass with Diablo? I'm willing to have to uninstall everything (I only play on Battle.Net since there's better stuff on there and I can reset all the bosses, so no worries about loosing my characters), but only if there's no other option.
