activerecord-sqlserver-adapter Gems Not Found HELP!!

Hi there,

I'm running ROR 2.x on Win32

tried to run gem install activerecord-sqlserver-adapter --source
http://gems.rubyonrails.org and get this:

D:\>gem install activerecord-sqlserver-adapter -source http://gems.rubyonrails.org
Bulk updating Gem source index for: http://gems.rubyonrails.org
ERROR: While executing gem ... (Gem::GemNotFoundException)
    Could not find activerecord-sqlserver-adapter (> 0) in any
repository

Also tried -s instead of --source

D:\>gem install activerecord-sqlserver-adapter -s http://gems.rubyonrails.org
Bulk updating Gem source index for: http://gems.rubyonrails.org
ERROR: While executing gem ... (Gem::GemNotFoundException)
    Could not find activerecord-sqlserver-adapter (> 0) in any
repository

HELP! I need to get this gem for an installation as soon as possible
