adventureworks application error

I am using ms sql server 2005 Enterprise Evaluation Edition, and I can use the other sample dtabases, like pubs, northwind, but not adventureworks
I tried diffrent ways,
I am very new to this, and I try before I ask, and I had to give up,
Here is what I did
when I installed adventureworks it was like 166 mb. big
And when I tried to use it with visual studio, every time I want to drag a table from: data connections/adventureworks, and try to veiw it in borwser it gives me an application server error, and invalid object name

with northwind database works fine

then I tried executing instawdb.sql located C:\Progam files\Microsoft SQL Server\90\Tools\Samples\AdventureWorks OLTP, from Sql server management studio,
And it finishes with errors, and is only 122 mb. big

This line in red:
Msg 4861, Level 16, State 1, Line 1
Cannot bulk load because the file "C:\Archivos de programa\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\AWDB\Address.csv" could not be opened. Operating system error code 3(error not found).

and at the end this:
DBCC SHRINKDATABASE: File ID 1 of database ID 6 was skipped because the file does not have enough free space to reclaim.

last night I was thinking wether it might be my OS( usning windows xp), or server evalution edition

Does anybody know something about this?
I already google search and only found one person with the same problem, but there was no solution posted

You can download an installer for the AdventureWorks database or the new smaller AdventureWorksLT database here
