What's a thread? I came across MyCE as I was looking for help with a possible clash between iTunes and MixMeister (ion) ez vinyl converter. Apparently files are missing from my iTunes and I'm advised to reinstall iTunes but my computer tells me the administrator won't allow it. Who's the administrator? My name was to have been rogerdigitallynaive but there was not space. So you see my problem. I often find things easier to understand when explained by someone just above my level rather than an expert. So how do I get to the bit about iTunes / MixMeister? What's a tag?
