For those who've been having the problem I was having with email validations and error messages, this is the reply I got from them
Thank you for your inquiry. This problem with your email address being marked as unvalidated was caused by LiveJournal's email server being incorrectly listed as a spam site on a few anti-spam services that are used by email providers and ISPs to filter out spam -- this usually happens due to the sheer volume of email that LiveJournal sends out for its users (comment notifications, other subscriptions, etc). When our server is listed at such spam sites, messages are not delivered to the recipient and instead create a huge volume of error messages back to us, which then triggers the email address to be marked as unvalidated.
This issue should now be resolved at this time, as we have worked with these sites to get our server removed from their lists. Your email address for your account is validated at this time, and you should have full, normal access to your account.
It does look like it's been resolved for me at the moment. Hopefully!
