cu8 fail step 15 of 17

I can't get cu8 installed and now my exchange server is behaving very strange I can connect to my outlook 2013 clients but can't receive any email ( internal or external). I checked all service and are running.

I got this error when it errored out.

Error:
The following error was generated when "$error.Clear();
          $fe = get-ActiveSyncVirtualDirectory -server $RoleFqdnOrName -DomainController $RoleDomainController -ErrorAction SilentlyContinue;

          if ($fe -eq $null)
          {
            new-ActiveSyncVirtualDirectory -DomainController $RoleDomainController -Role ClientAccess;
          }
          else
          {
            update-ActiveSyncVirtualDirectory $fe -DomainController $RoleDomainController -InstallIsapiFilter $true
          }

I have two activesync directory on IIS cause we don't want to allow ecp access from outside network.

we are running exchange 2007 and exchange 2013 in environment. we have plan to take 2007 out later once all mailboxes are transferred to exchange 2013. we have almost all mailboxes on 2013, but there are some service and distribution mailboxes on 2007.
