Hey guys, It's been about a month, nearing two, and I have not found one SINGLE fix for this! It ran fine for about 2-3 months before it stopped working and posted this message: The iTunes application could not be opened. An unknown error occured. (-50). What does this mean?! I tried doing this on my laptop as well, but poof. After adding Led Zeppelin, same error popped up. Is this Apple's way of saying "F*ck Windows, get a Mac." or is it my own fault? Oh, I keep my music on an external 500gb hard drive if that matters. Yes, I've tried every single fix out there. iTunes.bat doesn't work, editing registry keys doesn't work, uninstalling and reinstalling doesn't work! I feel as though Apple is pressuring me into buying a Mac. Can anyone help me, please?!
