Hi,
I suggest you to delete cookies and temporarily files from your web browser software. If you are using Internet Explorer 6, 7 or 8 as browser, then visit the link given below to get information about optimizing it:

In case you are using Mozilla Firefox then follow the link given below to optimize it:

Once you delete cookies and temporarily files, restart your computer and try to edit your website.
Note: If you have re-delegated any domain to your Microsoft Office Live account and have not completed re-delegation process then also you will receive an error message while editing your website. So, I suggest you to follow below link for completing re-delegation process:

Note: As a workaround, I suggest you to make fourth level domain as primary domain of your account so that you will be able to edit your website. After completing re-delegation process of your domain, once again you can make your re-delegated domain as primary domain of your account.
Follow steps mentioned below in order to make fourth level domain as primary domain of your account:
1. Open http://officelive.com website.
2. Click on sign in link at the top right corner.
3. Enter your Windows Live ID and password then click on sign in.
4. On the next page, click on “Manage Domains” under “Build Your Web Site” section and then click on “Make Primary” adjacent to fourth level domain.
5. Now, you will be able to edit your website.
If this issue still persists then contact Microsoft Office Live support team by following link:
