Ok, I realize that my last fear was correct: After finally finding the installation instructions and explicitly reading the message to first remove the free version I did as I was told – and finally managed to install the thing – including key, activation and all.
Only the promise that nothing would be damaged was not really true: I have “categories” for my files, and these are still there. Then I had download pages supposed to show the files by category – and this was not any more true: all download pages were empty! The files are physically still in place, but not any more linked for download from my site, so the statement that I am not going to lose my data is so far correct.
I saw then that there was some “missing widget”: wpdm_catpacks… that was obviously the thing that should do the trick of displaying the packages. I removed it and added instead the “WPDM Categories” widget that looks like the “Pro” version of the old one.
Only the problem is that I still cannot see my categorized download packages as before! There may be some tricky options somewhere that I still need to change!??
Ah well, that’s it: I do not need “WPDM Categories”, but rather “WPDM Packages by Category”! That brings it back indeed.
Only thing that is still a bit disappointing: I read that upload limits on file size would now be gone with Pro – but I still see that if I want to add some download items, files of more than 16MB cannot be uploaded directly: I need to use the “plesk panel” of my provider, put the files somewhere in a folder, and then “browse” to get them attached to a package – just like it was also with the Free version…
