I can not find this version of DeDe:

DeDe 3.50.02 build 1619 - full (with new DSF and DOI v2.3)

does anybody has a working (!) link so that I can add it to the AntiCrack download section ?

no, I donīt think this is a "warez" request

and yes, I have read the forum description:
"Do not ask where to get the Tools of our Trade. Do not even think about asking for them."

But since the DeDe site seems to be down,.....

Ok,

I have contacted DaFixer and here we go:

http://www.anticrack.de/modules.php?op=modload&name=Downloads&file=index&req=viewdownloaddetails&lid=3843

Try DaFixer's mirror site: h++p://dede.zadnik.org/IndexDF.html
There is DeDe 3.50.03 build 1625 available, check attached file for improvements
