Hi,

  I'm migrating a current umbraco site to Softsys hosting and are encountering an error that I can't solve.  
  I'm recieveing  the error "Could not load file of assembly (dll name of file in bin directory, i.e. umbraco.DataLayer, AjaxControlToolkit, umbraco) or one of its dependencies.  The located assembly's manifest definition does not match the assembly reference".  
   I've enabled full trust and allowed read/write permissions for the Network Service to the wwwroot folder and tried a variety of other things.  Any suggestions or ideas as to what could be causing this?

Thanks for your help!

Zac
