This suggests that you have put a password in database.yml, but the
error suggests there is no password.  Is there a password in
database.yml?

Have you checked that you can access the database via mysql using root
and whatever password is in this file?

I *think* that you may need to restart the server if you change database.yml.

Finally instantrails is very old, unless it has been recently updated.
 If you *must* do development on Windows then I think railsinstaller
is currently recommended.  Most would say that it is better to use Mac
or Linux (I use Ubuntu).  It is possible to do the development in a
virtual machine such as vmware or virtualbox running Ubuntu on the
windows host if you must use windows.

In a ''ruby console'' window you can use the mysql commands. 
You should
be able to do something like ''mysql -u root -ppassword
library_development''
If this does not work it means you have a missmatch between the password 
and what mysql has as the password.

If that works you might look closely at the database.yml.  It is picky 
about format and tabs cause problems.

Can you access the database ok using MysqlAdmin?

InstantRails works fine within its limitations.  I use it all of the 
time for my limited purpose.
