CRM_Mailing_BAO_Mailing was changed in 4.6.33

[Czollli]

Hi,

on the latest 4.6 release I am getting the following error:
Call to undefined method CRM_Mailing_BAO_Mailing::getTemplateTypes()
when the extension is enabled and I try to create new Mailings or continue draft one.

I am using version 2.0.
Could you have a look?

Thanks
