Error while creating report in DM

Hello everybody,

I am trying to generate a Word report. When I create all my chapters and fill content then hit "create", I get the following error:

Error during rendering document: 'Could not load file or assembly 'SAP.DM.Plugins.Sdk, Version=10.1.1.2, Culture=neutral, PublicKeyToken=0e672327d29f94bc' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)'

Any idea ?

Many thanks in advance
