Redmine

hi,

i'm a RoR n00b, and i'm trying to install Redmine on a Windows box by following the installation guide in the wiki. I'm having a weird problem and i can't find anything in google.
I have ruby 1.8.6 and RoR 2.1, and the Redmine files are in C:\redmine.

When i run 'rake db:migrate RAILS_ENV="production"'.

The output i get is this:

C:\redmine>rake --trace db:migrate RAILS_ENV="production"
(in C:/redmine)
Invoke db:migrate (first_time)
Invoke environment (first_time)
Execute environment
Execute db:migrate

My problem is this: As far as i can understand there are 92 migration tasks that are supposed to be done, yet my migration ends on action 3 and i don't even get an error message. That's why when i run 'rake redmine:load_default_data RAILS_ENV="production"' i get this message:

Error: Mysql::Error: #42S22Unknown column 'roles.builtin' in 'where clause': SELECT * FROM `roles` WHERE (`roles`.`builtin` = 0) LIMIT 1
Default configuration data was not loaded.

Could this be a Redmine issue, or a RoR version issue? [The installation guide says i should have RoR 2.0.2, and I have 2.1 but i didn't think it would lead to a stupid problem like this] Or perhaps some other weird issue?

As i said i'm a RoR n00b so any suggestions or tips will be very welcome.

Thanks
