Query timeout expired

Hi,

I have written a query in ssis script component which inserts 3,00,000 records into a table. When I run it, I get QUERY TIMEOUT ERROR

[Script Component [1]] Error: System.Data.OleDb.OleDbException: Query timeout expired
   at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e)
   at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PreExecute()
   at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostPreExecute(IDTSManagedComponentWrapper100 wrapper)

I have changed timeout option to '0'(no timeout) in sql server. It worked fine on day1.

But when I tried it again I am getting same error. PLZ help in this

Thanks
