Error: object reference not set to an instance of an object

Hi Gurus,

We recently upgraded from SP 10.0.5.2 to BPC MS SP 10.0.16.0.

While the Admin client is working, I am not able to connect to the EPM addin. I am getting an error message stating that : object reference not set to an instance of an object .

I checked the dimensions and hierarchies and they look fine.

Is there a work around for this?
