simple security problem with database

hi,

So I just finished building a website and heres the error, its a simple website with
profiles for people and this is what shows up while adding a profile, it all works no
problem on my computer.

The RunNonQuery() just opens a normal connection on the database, that ends up in a new filestream somehow,
but I don't understand how that causes a problem!!

There was an error:System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Security.SecurityException: Request for the permission of type
'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral,
