Layout 2018 upgrade install and export issues

Im on win 10 and am getting the error even with a totally blank layout doc - the template I’m using is one of the std templates that you get when you install LO / SU and I haven’t put an su model into it. I just go to export pdf and get the error msg I show a screen grab of above.

Personally I do 99.9% of my dimensions in LO - it gets too cluttered in SU and is just not presentable IMHO, but each to their own. Having tested in a blank doc I’m very doubtful that the issue is related to dimensions in SU but perhaps someone can shed some light on this.

The print to pdf is a work around but is not ideal - it’s strange that the error just popped up one day in su 2017 and still persists despite a full uninstall and reinstall (as admin). Anyone there from Trimble? @trent, @Marc? Throw me a bone will ya? :thinking:
