Hi Roland,
Finally got it working last night. Removed the C:/xampp/htdocs/AGH part. So the only part of the part that was left/used was stories/virtuemart/product
FYI I attached the log-file.
Another 'fact' that might interfere is that working local probably makes the processing way slower. You don't see messages from your (local)host anymore, but it looks like Joomla/CSVI is still processing in the background. So you have to be patient with seeing the results of your import efforts.
Thanks for your help. And the program is really awesome!
