Unable to delete a CM update package

Hi,

I have a "SP1 CU 3 - x64 client update" package in SCCM. I was unable to do anything with it due to it being locked when the the console crashed. I have freed it up however when I try to delete it I get the message:

"Cannot edit the object because it is waiting for replication updates".

I've waited but it always shows this message. The package source location does not exist on the CAS (where I'm trying to delete it).

Your help is appreciated.

Thanks.

David.
