Forum: Ruby on Rails no metadata found in activereocrd-3.2.9.gem when running bundle install in a rails 3.2.9

m a newbie in rails. working on Windows 7, 64 bits. Installed my
environment through RailsInstaller. latest version ofcourse. When 
creating
a new project, (keeping the gem file as default) and having the bundle
install run, am getting the error

gem::package::FormatError: no metadata found in
D:/RailsInstaller/Ruby1.9.3/bin/cashe/activereocrd-3.2.9.gem
and error occurrend while installing activerecord (3.2.9), and bubndler 
cannot continue.
Make sure that gem install activerecord -v '3.2.9' succeeds before 
building.

I tried to run the gem install activerecord..as instructed still bundle
install does not work and i cannot run the rails server. (rails s)

When changing the rails version in the app gem file to 3.2.8 instead of
3.2.9 everything seems to work and the rails server runs succefully. 
What
is wrong?
