@turbofandude I still have the same problem (Yes, I already installed the en-US windows language pack). The logfile tells me this about Vocal Dispatch:
LSPD First Response: VocalDispatch, Version=1.5.2.0, Culture=neutral, PublicKeyToken=null
LSPD First Response: Creating plugin: VocalDispatch.Main
LSPD First Response: VocalDispatch: Encountered an ArgumentException.
