Tried Good vs Evil and I can normally open it in toolset.
The 1.69 critical rebuild will uninstall community patch but oterwise it should be okay - but given your issue... try run 1.69 again, and open/play Good vs Evil. If it works try install community patch then. If not, the only thing that comes to my mind is new clean install. The diamond edition is bugged it appears like 1.69 but its missing many files. Are you sure you ran the 1.69 critical rebuild at all? Community patch 1.70/1.71 unfortunately doesnt contain the 1.69 so you need to install 1.69 first.
cep is only a collection of haks, no problem with patches can be installed anytime
