Update error: Key column 'shout_id' doesn't exist in table

[plainhavoc]

I have renewed license, and attempted to download the latest version. Upon installation, I keep getting the error: "Key column 'shout_id' doesn't exist in table" and it will not let me install. Any ideas on how to fix this other than manually creating the column in the database?

The upgrade script should rename all affected columns. Which table exactly the error mentions?

I think part of my problem is that the subscription may be different between two different computers. Signing in here does not even show orders on the account

This is all it gives when trying to install the zip file that was downloaded

Installation script upgrades tables from the latest 2.9.5 version only. If you previously had an older version, script will fail. In this case you have to uninstall old version, remove all its files and related tables from database. When you done, installation will run smoothly.

Thank you, that worked brilliantly!
