After a recent install of courier beta on umbraco 4.5.2 it cant find the courier providers

This is on W2k3, IIS6, Umbraco 4.5.2 .net 3.5 buid. There has be no configuration changes yet, fresh umbraco install, followed up by fresh Courier beta 2.0 (227) Seems to require to run under .net 4.0 for courier 2.0 though. After my installation of courier, if I click on the courier top node in the courier section, I do not get the "Repositories" and "Revisions" links as I would expect, it comes back empty. Looking in the event log I see:

  Exception type: ProviderException
