Error - Easy Blog Updae

Hello,

I am trying to update 2 Easy blog on 2 websites and get the following error:

Warning
Update path does not exist.
Message
Error updating COM_INSTALLER_TYPE_TYPE_.

So I went to your website, logged in, downloaded the basic install package and when I went to install was prompted to do the setup, so stopped as I didn't want to overwrite the settings I have already configured.

Can you please advise on what course of action I need to take in order to complete the update.

Thanx!
