Yes, the links for this are down.
When I said the links worked for me, I put them in JDownloader and it said they were online I didn't go any further because I didn't want to download them again, sorry for giving the wrong impression.

As for re-upping them it might be best to wait for Harmy to do it, where else can you upload 2GB files to other than the Czech site?
