I'm having a serious issue that began a couple of weeks after I download Mac Mountain Lion. The issue consists of every 10 minutes, an error that says "Keychain "login" cannot be found to store ( then a serial number or some authentication number of some kind ) server certificate data". It pops up every 10 to 15 minutes and I can't understand how to get it to go away. Below it there is a "Close" and "Reset to Defaults". I go to Reset to Defaults and it sends me to another error of the same kind, and I reset it by putting my password in and then it sends me to yet another error of the same kind. There are two different kinds that look the a little different and I just keep entering my password but nothing is ever fix, they just keep popping up again. There are also been an issue, that I am pretty sure is linked with this, where my Macbook won't store passwords as well and I constantly have to put many of them in. I am not sure how to fix this, but if someone can help me it would be greatly appreciated as it's really getting on my nerves and I don't know what to do. Thanks in advance.
@ChickenRaider: have you tried changing your admin password under Accounts?
I did a quick search and found that many user who tried to access SkyDrive faced the similar error: Are you also trying to access the Skydrive?
