I Can't Log-in in Mybloglog Account

Just a few months ago, I changed the yahoo email log-in in mybloglog account. I also know that MyBlogLog is now owned by yahoo. You can also log-in with your yahoo account to mybloglog account using the same password. Since I changed my email sign-in, I have a hard time to log-in now because it says it is not the correct log-in. I even tired both of my yahoo email, the old and new which I use to log-in but it always says, I need to create a new account..I tried to send an email to their contact but it won't go through..i guess I need to create a new one if it won't work again...what a time consuming..back to the start...have a great evening to all..time to slowly sign-off!!
