SQLITE3 error

I keep getting the following error when trying to use sqlite3 with Ruby.

"./sqlite3.dll: 127: The specified procedure could not be found. - Init_sqlite3 (LoadError) ./sqlite3.dll from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' ..."

I'm using Windows XP. I tried reinstalling:   ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]   rubygems 1.3.1   sqlite3.dll and sqlite3.def from sqlite.org, version 3.6.4.

The ruby program I'm running is:

require "rubygems" require "activerecord" ActiveRecord::Base.establish_connection(:adapter => "sqlite3", :database => "test.sqlite") class Account < ActiveRecord::Base end account = Account.new account.username = "cpytel" account.save

Does anyone have any suggestions? This error message appeared before in this forum, and the cure was to update the code. I am using more recent versions than were available then.
