help seeding my data base

hi i am trying to seed my database using
rake db:seed
fist error I had was
uninitialized constant faker
so I added the faker gem
second was
uninitialized constant factory
so I added factory_girl_rails gem
third was
uninitialized constant license
so I added license gem
now I get the error
undefined method `create' for License:Class

can anyone help I've been stuck on this for 2 days now

Thanks

It might be helpful if you showed us some code. Preferably the bit
that is causing the error.
