iTunes Producer unable to get password from my keychain When I try to open iTunes Producer, I get an error stating, "We are unable to retrieve your password from the security keychain." I recently deleted the folder in my keychain library while trying to fix another keychain problem that I was having. The previous problem was that a large number of programs (calendar, chrome, etc.) had problems with the keychain. I fixed that problem by resetting my iCloud and computer keychains.

I am currently running OS X Yosemite on my iMac and have not had any problems prior to these two keychain problems. I haven't downloaded anything that was even remotely dangerous. I've run keychain first aid and reinstalled the program. I've also deleted the library file again. At this point, I have no idea what to do. I've gone through and opened every other program on my computer with no problems at all.

Thank you for any advice. I've spent the last two days googling and I guess that I'm the only one to have ever encountered this problem :(
Looks like your Keychain has corrupted.

Do you get this error "Preferences Error: Could not load Accounts preference pane."

I have a solution here

Search for "Keychain Access" and a window as shown in the picture above would appear. Select the account which is troubling you.
Delete it/them and restart.
Moreover you can review any used accounts and remove them from here too.
