New Post: How to host bugnet issue tracker on shared server?

I try to host bugnet issue tracker on my server. I am using arvixe web server.

http://epstechno.com/issues/Install/Install.aspx

I get following error in page.

You must specify a valid default data provider.

I get following error when i run following script in server database

script:
GO
/ Object: User [Username] Script Date: 05/30/2013 11:40:36 /
CREATE USER [Username] FOR LOGIN [Username] WITH DEFAULT_SCHEMA=[dbo]
GO

__error:
Msg 15007, Level 16, State 1, Line 2
'Username' is not a valid login or you do not have permission.__

Is there any other way to host bugnet issue tracker on my server?
