Workflow Activities not working in WIN SVR 2008

Aug 16, 2010 at 9:16 PM

I have MOSS 2007 SP2 Running on WIN SVR 2008 STD and I cannot get any of the workflow activities to work.  These safecontrols are listed in the web.config as follows: 

<SafeControl Assembly="DP.Sharepoint.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0298457208daed83" Namespace="DP.Sharepoint.Workflow.InfoPath" TypeName="*" Safe="True" />
<SafeControl Assembly="DP.Sharepoint.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0298457208daed83" Namespace="DP.Sharepoint.Workflow.Install" TypeName="*" Safe="True" />
<SafeControl Assembly="DP.Sharepoint.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0298457208daed83" Namespace="DP.Sharepoint.Workflow" TypeName="*" Safe="True" />

and this is added to the appropriate section in the web.config"

I've also added the following : <authorizedType Assembly="DP.Sharepoint.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0298457208daed83" Namespace="DP.Sharepoint.Workflow" TypeName="*" Authorized="True" /> to the <System.Workflow.ComponentModel.WorkflowCompiler><authorizedTypes> section in the web.config. 

All help appreciated.
