Hi.
I may not be remembering correctly but I think I started having trouble like this when I installed the update. Try uninstalling entombed completely, I mean remove every trace of it then install entombed without the update and see if that helps. I know this is not ideal but if it makes you feel any better the update didn't add any new features or sounds or anything like that it was mostly a bug fix update.
