Unable to modify or create Protection Groups in DPM 2012 R2 - Error: 31220

Question

"DPM failed to apply the required policies to this protection group since the recovery point limit for this DPM server has been exceeded. (ID: 31220)"
I am trying to add new data sources to our DPM server and continually run into the above message. I get the same error whether I attempt to create a new Protection Group and add the data sources to it... or if I attempt to modify an existing Protection Group
to add data sources to it. I can guess that the obvious answer is "You have too many data sources or to many recovery points for the server to handle..." If that's the case, I need to figure out how to tell how many I have. As best as I can figure
myself, I have less than 150 data sources and less than 2500 recovery points/snapshot/express-full. If there is a tool or a command that I can run to tell that, I'd be grateful to anyone who can point me in that direction.
I have tried to remove inactive member servers that no longer exist from our Protection Groups... no effect.  I have tried to completely delete the removed server's data from replica... no effect.  We began seeing this issue in 2012 SP1, so I ran
through the upgrade to 2012 R2 hoping that it would resolve the issue... no effect.  I am able to remove members from our Protection Groups, but if I try to add an entirely new member or even just a single DB on an already protected member... fails with
above message.  I also tried to adjust the retention and backup schedule... fails with above error.
Other than the stock answer from Microsoft that I am truly exceeding some limit, is there any other underlying issue that can cause this to be mis-reported to me?  I hope that SOMEONE has an answer or guidance for me.

Hi,
Another DPM PowerShell script - this one allows you to delete older recovery points for a selected datasource without having to modify the PG.
