Good match. My last successful run was on APR22, the first failure on APR30.
For the root cause I am not sure I can follow. But I can let you know once it works again. 
Just now it still failed. BTW, version number 3.2.7 refers to GDExporter, doesn’t it? Does GDExporter also output that version? So far I am sure to run the latest available version but cannot tell exactly which one it is…
