Can't delete project service application instance

Question

Hi!
First, sorry for my english.
I'm trying to delete project service application instance with no luck. I tried to delete service app accordingly with this topic (http://social.technet.microsoft.com/Forums/en-US/d03219d0-9748-43ef-9c5e-b9006bcaf354/cant-delete-project-web-app-or-service-application?forum=sharepointadmin)
and i've got "Object reference not set to an instance of an object." error after calling Delete method. I tried to delete service app from central administration and also tried to create a new one, but i still got this error in both
cases.
I'm using Sharepoint 2013 SP 1 and Project Server 2013 SP 1
Any suggestions, please

Hi Konnie,
Look for any orphan PWA instances in the farm by running the below commands:
> Retrieve the List of PWA instances in the farm including the orphaned ones: 
$serviceapp = get-spserviceapplication | ? {$_.TypeName -like "*Project*"}
$pwainstances = $serviceapp.Sitecollection
$pwainstances | ft name, id
> Look for the properties of the instances by running the below commands and find the one which is orphaned
$toberemoved = $pwainstances | ? {$_.Id -eq "491b0247-fb73-46ac-89ac-fd39db184995"}
$toberemoved
> Once the orphaned PWA is identified delete the orphan entry by running the below command
$toberemoved.delete()
