Tried deploy - get a "Forbidden" message

Hi There:

I am trying to figure out a good way to deploy drupal website content updates (i.e. mysql database changes) from a development server to our production server. Currently, I just take a mysql dump of the dev database and restore this dump to the production mysql database (so, in essense, the entire dev mysql database is copied to the prod database, and all the changes that were done on "dev" are thus deployed to "prod"). Unfortunately, there are some issues with this because I have to take the prod site off-line briefly, otherwise errors will be thrown during the database restore. So, I thought that perhaps I could use this deployment module to deploy content. I followed all the instructions, but get a deployment log error message that says 'Forbidden' - i.e. the deploy doesn't work.

Does anyone know what I might be doing wrong? Also, will this deployment module actually deploy "content" changes I've made to some of the pages of my website? (I wasn't sure, I'm just trying to deploy the content type "Page"). And, on a bigger scale, are there any other good ways out there that Drupal people are using to deploy changes (i.e. update the prod database with changes from the dev database) without having to take the prod site off-line - like some sort of syncing code/application (that is free)?

Thanks alot,
