Could not find type in ReflectionUtil.CreateObject: Cognifide.PowerShell.SitecoreIntegrations

Hi,

i get this error when i try to open Powershell_ISE after installing SPE 3.3 version.

FYI: sitecore 8.1 version & decompiling "Cognifide.PowerShell.dll" i couldn't identify such a namespace. Even my config remains unchanged.
