Error Syncronizing Database

Hi, I originally posted this in the SQL Compare forum, it actually occurred when I was using the toolkit.

I am trying to syncronize 2 databases using a snapshot from one database and comparing against another. The compare works fine but I'm failing on the ExecuteBlock statement with an error:

An unhandled exception of type 'System.ArgumentException' occurred in microsoft.visualbasic.dll

Additional information: Argument 'Prompt' cannot be converted to type 'String'.

I am using .net Framework 1.1 and SQL Server 2000

Here is my code:

Sub SynchronizeDatabases()

Dim db1 As Database = New Database()
Dim db2 As Database = New Database()


db1.Register(New ConnectionProperties("KROCK-LAPTOP\RESOURCETRACKING", "RT1", "x", "x"), Options.Default)
db2.LoadFromDisk("c:\RT1Production.snp")

Dim differences As Differences = db1.CompareWith(db2, Options.Default)

Dim difference As Difference

For Each difference In differences
difference.Selected = True
Next

Dim work As Work = New Work()


work.BuildFromDifferences(differences, Options.Default, True)


Console.WriteLine("Messages:")

Dim message As Message

For Each message In work.Messages
Console.WriteLine(message.Text)
Next

Console.WriteLine("Warnings:")

For Each message In work.Warnings
Console.WriteLine(message.Text)
Next



Dim block As ExecutionBlock = work.ExecutionBlock

Console.WriteLine("SQL to synchronize:")

Console.WriteLine(block.ToString())

'run the SQL
Try
Dim utils As Utils = New Utils

utils.ExecuteBlock(block, "KROCK-LAPTOP\RESOURCETRACKING", "RT1", false, "x", "x")
Catch sqlexc As SqlClient.SqlException
MsgBox(sqlexc)
Catch exc As Exception
MsgBox(exc)
Finally
db1.Dispose()
db2.Dispose()
block.Dispose()
End Try

End Sub

Any input would be greatly appreciated.
