Nope, haven't seen that, but then I haven't touched much yet with the new CK either. Seems to be indicating a possible problem with a loose file resource?
I was curious enough to backup Skyrim, reinstall everything, and run Skyrim and the CK with nothing added. Same thing.
A dependency check suggests a couple of system dll files missing. One I know to ignore. The other is gpsvc.dll. There is no 32 bit version of that file on Windows 7 64 and I can't see why they would link against it anyway.
Assuming it's related, I'm going to ignore it and carry on.
