I just opened iTunes after turning on my computer and it came up with a screen saying "Welcome to iTunes" and promted me to go through a few screens to "begin using iTunes" like I just installed it or something, when in fact I've had it on this computer since I bought this PC. Now fonts and stuff are a tad bit smaller and some categories and such are not there anymore. I understand I can easily just change the preferences back to how I had them but why would this reset? What is with this going on? Has anyone else had this problem? Bitter.
