Not sure that matters at this point, the messages appear to be pointing to 2 unrelated failure points.
I have an update.
We have identified the problem and are working on a new Windows Defender Offline release.

Windows 7 64 Bit. I have been using Windows Defender Offline on a USB thumb drive (4 GB, uses less than 1 GB) for years without problem. Last week updating Windows Defender Offline definitions to an already working USB thumb drive seemed to install correctly. When I boot to the USB thumb drive the program boots and runs but I get the message the "definitions out of date", and it will not scan the computer. I tried formatting USB thumb drive and then installing the whole Windows Defender Offline with definitions instead of just updating the definitions to the already working USB thumb drive. Everything went correctly, the size of the download appeared to be correct. I booted to the USB thumb drive and still got the message "definitions out of date". Since the Windows Defender Offline program started offline, and was installed onto a completely formatted USB thumb drive, it must have downloaded and installed correctly but the definitions are still "out of date". Are the definitions being updated by Microsoft or has the program been discontinued?

2016-05-13T08:34:02+00:00 I am having the same problem with the WDO updates. Upon further investigation I have discovered that the mssstool is properly updating the definitions on the WDO media USB. You can determine this by examining the properties of the MPAM-fe.exe file on the USB, after running a current update using the mssstool. Click properties and then the detail tab for the file to see its version number. The version on todays date (05_13_2016) is 1.219.16650. If you Microsoft update program is functioning, you will find that same version on your internal Windows Defender program, which will function properly. However, the OFFLINE program on the USB will not. It says that the definitions are not up to date! Shortly after Windows 7 came out, this program's predecessor "Microsoft AntiSpyware" ceased to function on Windows XP. This may be what is happening now on Windows 7. Think Windows 10.
