ASP.NET MVC2 Guid persistance issue

I have an ASP.NET MVC2 application on .NET 4.0 and built using VS 2010 that has two tables (amongst others), an employees table which has the following columns: Firstname, MiddleName, LastName, NationalID, EmployeeType, MobileNumber, Email and UserId.

The userId field is a foreign key from the aspnet_users table which happens to be a guid. I am trying to persist the employee details for a selected user but cannot do so as I am getting an error.

The guid value for the selected user can be extracted and displayed using the ViewData dictionary. The userId guid value is 23aa8cd9-7552-403c-8c99-fcdd611cb188.

I would like to persist this value together with other employee properties but when I submit the form I get the error shown below. I am also using EF4 for my model. Here's the stacktrace:

System.Data.UpdateException was unhandled by user code
  Message=An error occurred while updating the entries. See the inner exception for details.

To me, this message means that you are adding a string that is too long for one of your char/varchar fields:

    String or binary data would be truncated.
    The statement has been terminated.
