[VB.NET/Crystal Reports] Table cannot be found problem

hello!

i have encountered an exception that says "Table cannot be found".

テーブルが見つかりませんでした。 System.Runtime.InteropServices.COMException (0x800002C5): テーブル 'OKKC401P_PRT' が見つかりません。
ファイル C:\DOCUME~1\irvin\LOCALS~1\Temp\Okkc401 {188FDE00-417D-4CF6-B50A-E54D082E8BFF}.rpt のエラー :

(sorry its in japanese though)

and my code looks like this:

logOnInfo = REPORT.Database.Tables.Item("OKKC401P_PRT").LogOnInfo

Dim crDatabase As Database
Dim crTables As Tables
Dim crTable As Table

Dim connectionInfo As New ConnectionInfo

crDatabase = REPORT.Database
crTables = crDatabase.Tables

connectionInfo = REPORT.Database.Tables.Item("OKKC401P_PRT").LogOnInfo.ConnectionInfo
connectionInfo.DatabaseName = Server
connectionInfo.ServerName = Server
connectionInfo.Password = Password
connectionInfo.UserID = username

For Each crTable In crTables
logOnInfo = crTable.LogOnInfo
logOnInfo.ConnectionInfo = connectionInfo
crTable.ApplyLogOnInfo(logOnInfo)

Try
REPORT.Database.Tables.Item(crTable.Name).Location = username & "." & crTable.Location
Catch ex As Exception
Log_File_Up("setDatabase", ex.ToString)
End Try
Next

ive checked the connectivity of the crTable and it returned TRUE, i guess a success. but when the location is assigned, I get the error above.

anybody who has a solution for this one.
