The only problem I had with the online tool is that it would only allow 15 segments. Said that my itin was invalid for too many segments. Removed the last one (DOH-CAI) and it was fine. (Since it's not until July, I assume that there will be schedule changes before I start, anyway.)
The online tool definitely allows 16 segments. However its error messages are not the best.
The message was actually telling you that you had too many segments (5) in Europe/Middle East, where only 4 are allowed.
