Ok, ive managed to get it importing the titles ok, I copied all my data into your sample file and it worked?
Now I have another problem, the PDFs within the packages seem to be ok but the zip files I also have in the packages seem not to be valid, they have a strange blue icon with “_BL” on them and the package won’t download it just breaks and says there has been a critical error on the website. However if I remove the zip file and use the “select from server” button and re-save the icon turns to a zip icon and it dopwnloads ok.
I tired this on your demo site too and got the same thing.
