Sequence contains no matching element

[pab74]

Hello, I am trying your xrmtoolbox. Looks useful, but I am facing several problems. I found out that 99% of the time if you map a field and then modify or unmap it, then the plugin crashes. In my last attempt I added the currency field, set to "fixed lookup", then I unmapped it and it crashed. At this point the xml setting file failed to load because it was malformed. and so the plugin failed to start. I fixed it manually, reloaded the plugin and now I have the following error:
************** Exception Text **************
System.InvalidOperationException: Sequence contains no matching element

at System.ComponentModel.BackgroundWorker.OnRunWorkerCompleted(RunWorkerCompletedEventArgs e)
In any case, nice job, thank you for sharing
Kind regards
Paolo

I think I have resolved this, as it was due to like you say the file that got generated. Can you try the latest version 8.7 @pab74 ?
