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 filesMicrosoft SQL Server90ToolsSamplesAdventureWorks 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 programaMicrosoft SQL ServerMSSQL.1MSSQLDATAAWDBAddress.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
