I think the best option for you would be to make a backup of you Images folder and your database, and then scrub out 0.32 completely. Then install 0.33 from scratch, import your database and images folders, and then do the database modifications laid out in the wiki. Finally, run the installer one more time, then and only then, log in to the web gui. The only thing that I ran into after that is the TFTP settings that needed correction and for any clients that did not have an image associated I needed to open each host and select an image or the top dropdown option for none.
