Unable to create blog post - Perch Blog Sorry, that post could not be updated

I receive the above error when trying to add a blog post. I've updated both Perch and the Blog app to the latest versions and have followed Drew's instructions in the following forum post:

https://forum.grabaperch.com/forum/08-12-2014-perch-blog-create-post-issue-sorry-that-post-could-not-be-updated

According to my debug info there is a table missing:

SELECT u.*, r.* FROM perch2_users u, perch2_user_roles r WHERE u.roleID=r.roleID AND u.userEnabled=1 AND u.userID=1 AND u.userHash='0c16216208f1be986ba2c9f949b4f866' LIMIT 1
UPDATE perch2_users SET userHash='8f22db7169e55aa6107ed0f70afcac6c' WHERE userID=1
SELECT p.privKey FROM perch2_user_privileges p
SELECT * FROM (SELECT DISTINCT settingID, settingValue FROM perch2_settings WHERE userID=1 OR userID=0 ORDER BY userID DESC) AS settings GROUP BY settingID
SELECT * FROM perch2_categories c, perch2_category_sets s WHERE c.setID=s.setID AND s.setSlug='blog' ORDER BY catTreePosition ASC
SELECT * FROM perch2_blog_sections ORDER BY sectionTitle ASC
Invalid query: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'hispeed.perch2_blog_sections' doesn't exist
