Delete the object through tridion core service - tridion

Question

I am not able to delete the object through core service.
I am getting object reference not found error. I am able to create and get the object but delete functionality fails.
I am using this code:
var client = new CoreService2010Client();
client.ClientCredentials.Windows.ClientCredential.UserName = Settings.UserID;
client.ClientCredentials.Windows.ClientCredential.Password = Settings.Password;
client.Open();
client.Delete(TCMURI);
here's the error:

I had the same error and it was related to UGC.
I disabled UGC (commented out the model and editor in the config and the eventsystem.dll from ugc), restarted the server and everything worked.
Check the 'Tridion' Windows Event Log on the Content Manager Server. There is probably an error related to UGC. I think you need to contact CS to fix this, since the error is in the Eventsystem dll from UGC
