No, this are the wordlets - vars_wordlets_mods.cgi - I got that one...
I think it´s because this hack requires
"UBB 6.3 and Mod Wordlets 1.5" as shown on the first page.
http://dpk.b000.net/ That is the link for Mod Wordlets 1.5, but I can´t find it there.
That is my problem : I installed the hack with Multihack and corrected the errors myself (there were problems because I use the german version), then I uploaded all, CHMOD the new files 755, then I went in my forum details and chose "yes" for upload, cleared the cache - but nothing changed, there is no field where I can upload...
