ASP.NET migration problem

[Beto]

I'm migrating a .net application to a new server:

Old configuration:
- Plesk 8.1.1
- Windows Server 2003
- IIS6

New configuration
- Plesk 9.3
- Windows Server 2008
- IIS 7.5

I have to configure the application pool in "Classic Pipeline Mode" and not "Integrated pipeline mode".
After configuring the application pool I've got following message:

HTTP Error 500.21 - Internal Server Error
Handler "Plesk_Handler_0111005412" has a bad module "ManagedPipelineHandler" in its module list

Can anyone help me with this error?
