Got it. Did a few checks yesterday and I found a possible reason for the crash.
The error window itself is not a blocker, but a data format issue. I will fix those too but they should not crash the app.
I need a bit of time to package a new version, so this will likely this week-end. But I can send you the updated version directly, so you can check directly if my fixes work. ( and also be my QA for the new version :) )
