Create domain fails with plesk 9

[yucteam]

Hello,
I get the following error after an upgrade from 8.6 to 9

Error: Unable to update hosting preferences: Unable to reconfigure Web server: websrvmng failed: Filename: \\?\C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\50\isapi\web.config
Error: Cannot write configuration file due to insufficient permissions
In module
Exception type: System.UnauthorizedAccessException
at Microsoft.Web.Administration.Interop.AppHostWritableAdminManager.CommitChanges()
at Microsoft.Web.Administration.ConfigurationManager.CommitChanges()
at Microsoft.Web.Administration.ServerManager.CommitChanges()
at CInternalUtils.Commit()
at CIIS7ServerManagerBase.Commit(CIIS7ServerManagerBase* )

This happens when I try to create a new domain at the second step.
Step 1 asks for domain info and login, then I hit next.
Step 2 shows my defaut setup and once again I hit next and on the reload I get the error.

Quick notes: I ran the plesk reconfigurator with Correct Disk permissions and Check component and folders options without any success. And everything was working in 8.6

Any advice on how to fix this ?

Thanks
