I paid the money for idisk and had it working to some extent then apparently (probably after a couple of glasses of wine) changed the password. I keep getting a pop up box (see below) and even though I have had imac send me a password reset code to my email and reset the password yet again at mac.com and I seem to be able to access my email and the idisc files, apparently my offline idisk cannot sync with the one on line. I am not even sure the message I'm seeing is not from some other shareware or something. Or whether it could be something to do with keychain. But it is driving me nuts and I can't figure out how to contact imac help to ask what to do. Would appreciate any help. Here again is the message I keep getting: WebDAV File System Authentication Enter your user name and password to access the server at the URL "http://idisk.mac.com/zen_city/" in the realm "idisk.mac.com."
