Hi Batch,
The problem seems to recurring every few runs or so? Deleting the existing screenshots and xplogger file you mentioned earlier does seem to fix it.
Edit: It does not always fix it.
The latest error i got is as follows:
Could not run UI callable.
java.lang.NullPointerException <---- no idea what it means?
Hope this helps and you can advise on what to do to fix it.
Thanks!
