parser error - problems deploying a webservice

[Riga]

Hi guys,
I'm trying to deploy a WebService on a server.

Here's what I did so far:
1) Created a new website in IIS (on the port I want to use)
2) Shared that directory through windows so that I can upload stuff
3) Used the "Copy Website" function in VS2005 to copy the files to that folder

My error is as follows... Any ideas?:
Server Error in '/' Application.
