Hello everyone!  
I try run simple RoR application, I go to RoR default “hello page”,but I  
got error, when trying to open new views.  
Status: 500 Internal Server Error  
could not open database: unable to open database file  
C:/Ruby/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.3-x86-mswin32/lib/sqlite3/errors.rb:62:in  
`check' C:/Ruby/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.3-x86-mswin32/lib/sqlite3/database.rb:79:in`initialize’  
…  
and so on, long list

my database.yml is default:  
development:  
adapter: sqlite3  
database: db/development.sqlite3  
pool: 5  
timeout: 5000

But I am running almost the same configuration using Instant Rails  
without any problems/  
Has anyone met the same problem?

Have you installed SQLite3?
