OK, I've gone through the whole thread. At the moment, I am facing 2 issues:
1. After upgrading, when I download any of the files which had been uploaded prior to the upgrade, the file downloaded has a number as a previx, something like this:
63073-Bin Roye Aansoo.rar. Previously, when downloaded, only the title would appear, i.e.
Bin Roye Aansoo.rar. Is there some way to fix this?
2. Has anyone tried to import files after the upgrade? Because I've been trying to do so, and the path which I used to feed before for importing is no longer working, plus I've tried all alternatives I could think of.
The path which worked previously was: downloads/Original files/
I have tried the complete URL, i.e.
http://sitename.com/downloads/Original files/, as well as the address of the files on the server, i.e. D:\Webspace\*****\forums.pakfellows.com\www\downlo ads\Original Files
However, I just can't get the script to detect anything.
Could you kindly have a look at these, RS_Jelle? Thanks!
Update regarding issue 2: OK, this is a bit embarrassing...my apologies for spamming like this.

I noticed that unlike the previous version where simply we listed the allowed extensions, here we have the option to select detailed options for every extension. Once I entered the extension I wanted to import, it detected everything.
That leaves only issue no. 1.
