Can't log in to iTunes Producer
For some inexplicable reason, iTunes Producer doesn't want to accept my Apple account name or my password (the error message doesn't specify which one). This is the same account name and password I've always used, and the same one I used to log into this support forum. I'm using iTunes Producer 3.0 on a recent vintage iMac running OS 10.9.1. This is maddening because I'm so close to publishing my book. Any help would be appreciated.
