check your log, I had to delete the file in the APOC\Content\Paks - the pakchunk0optional-WindowsClient.pak file was problematic, just delete it and voila!

Hi all - this particular pak file error comes from having previous files leftover from prior play tests, so please follow the instructions here to ensure you remove all old files before starting with the latest fresh install from your download center of choice!
