2018-03-14 23:52:33 -0500 marked best answer Why does IDF Editor issue error "Run-time error '9': Subscript out of range," aborting on Save-as?

I have an IDF file that I exported from Design Builder (v.5.3.4.004). The Version listed in the IDF is "8.6.0.001". I would like to open this file in IDFEditor, and save it to get the objects formatted (grouped by class and in the IDF editor format.) When I open it with the IDFEditor v8.6.0, I got a warning that the file format is incompatible with the .IDD file being used, and with the IDFEditor version. I edited the Version to be "8.6" in my text editor, and that warning ceased. The IDF file appears to run fine using EPLaunch v8.6.0 (I am running it now: it was read with no issues....and still simulating fine so far).

BUT, when I try to save the file, it aborts during the process with the error: "Run-time error '9': Subscript out of range", once I click "Okay" on that error, the IDFEditor quits. (I can open the new IDF file that I was attempting to save, and it does contain a incomplete portion of the IDF.

Any ideas how I can solve this?

2018-03-01 15:03:43 -0500 marked best answer What air terminal unit types are allowed on a AirLoopHVAC:Unitary system?

I see that the diagrams in the section of the I/O reference on AirLoopHVAC:UnitarySystemshow only AirTerminal:SingleDuct:Uncontrolled. I have a file built by a colleague (which runs) that uses AirTerminal:SingleDuct:VAV:NoReheat for a zone served by an AirLoopHVAC:UnitarySystem. I am wondering if this is problematic.
