Weird Installation Error

Hi

I am running Windows XP with Service Pack 2.

I installed IIS and then installed Visual Web Developer 2008 and created a new
project in IIS with a blank default.aspx page.

I then had an error about the IIS metabase, so I ran the following command: 
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -ga
IWAM_HETZNER_EMThis fixed the metabase error, but now I'm receiving a new error
that reads the following:
 
Server Error in '/test' Application. 

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current
web request. Please review the stack trace for more information about the error
and where it originated in the code. 

Exception Details: System.NullReferenceException: Object reference not set to an
instance of an object.

Source Error:

Can anyone please help?
