Cannot get Hexdata to work

I have redshop and virtuemart installed, now what I wish to do is take the products and catagories from redshop and import them into virtuemart,
I cannot get a working csv file out of the exporter, and opening it I get this in the csv
"Warning: mysqli_query(): Empty query in /hermes/bosweb26b/b2406/nf.computermechanicca/public_html/libraries/joomla/database/database/mysqli.php on line 382:
null given Warning: array_unshift() expects parameter 1 to be array in /hermes/bosweb26b/b2406/nf.computermechanicca/public_html/plugins/hexdata/custom/custom.php on line 223
Warning: Invalid argument supplied for foreach() in /hermes/bosweb26b/b2406/nf.computermechanicca/public_html/plugins/hexdata/custom/custom.php on line 232
any help would be appreciated, thank you.

Hi,

Please check now your backend. I've corrected one of your profile i.e. Redshop categories. You can now import/export the data from this table. You need to correct the other profiles in the same way. You weren't including the fields in the profiles which are to be exported/imported. You can do so just by entering some name in the textfields.

Thanks

thanks for setting that up but after running the job I get this error.
DB function failed with error number 1062
Duplicate entry '' for key 'slug' SQL=INSERT INTO `btjzd_virtuemart_categories_en_gb` (`virtuemart_category_id`,`category_name`) VALUES ('4282','Axle - Rear Both Sides')

It's because you are trying to import the same records which are already there in database, "slug" is a unique table key, so remove this record from CSV and then try to import. If it doesn't solve your problem tell us what exactly you are trying to do?

Thanks
