Invalid Action - The selected action was not valid.

I download new MS CRM VPC (April 2009), When I browse the MS CRM Default organization (contoso)I discovered that we were receiving a very descriptive "Invalid Action: The selected action was not valid" error message.

Then, I checked the system's Application Event Log. LOL, I found the following error message:
Source: Current active key (KeyType : CrmWRPCTokenKey) is expired. This can indicate that a key is not being regenerated properly. Current Active Key : CrmKey(Id:e1a5b215-d01e-de11-9d16-0003ffd0167c, ScaleGroupId:00000000-0000-0000-0000-000000000000, KeyType:CrmWRPCTokenKey, Expired:True, ValidOn:04/01/2009 15:16:36, ExpiresOn:05/04/2009 15:16:36, CreatedOn:04/01/2009 15:16:36, CreatedBy:NT AUTHORITY\NETWORK SERVICE. Key Setting :

Fortunately, this problem was easily solved by running services.msc and starting the Microsoft CRM Asynchronous Processing Service.

Always look into Event Log messages for quick error resolutions (MS, Pls give more info, dont just put the kb link :( )
