OWA stoped working after Exchange Roll up 10 KB981407

I installed rollup 10 for exchange yesterday. I noticed that my OWA stopped working.
In Exchange Management Console --> Server config --> Client Access --> When I click on my exchange server the OWA, OAB tabs are blank.

If I go to IIS anc click on owa virtual directory I get the bleow error
There was a error while performing this operation
Details: The service cannot be started, either becauseit is disabled or because it has no enabled device associated with it.

On the UPDATEowa log I see
[14:40:12] * UpdateOwa.ps1: 4/27/2010 2:40:12 PM
[14:40:13] Updating OWA on server EXCHANGESERVER

[14:40:15] Getting all Exchange 2007 OWA virtual directories
[14:40:15] There are no Exchange 2007 OWA virtual directories.  Aborting.

Please help.

The IIS admin service was disabled, so I enabled it.
Then I realized that the path for OWA is pointing to
C:\Program Files\Microsoft\Exchange Server\ClientAccess\owa\Current
That must be the directory where it stores the old settings before an upgrade

It should be
C:\Program Files\Microsoft\Exchange Server\ClientAccess
When I changed that, everything started working.

Sorry I forogt to add,
I did remove KB98407 with no help.
I just found out that IIS admin service was disabled, I started the service. In my Client access OWA has appeared but it still doesnt open the page for me. The website keeps saying waiting for page to load and then it gives me http500 error.

Thank you,
