I am really pleased you posted here as I was beginning to think I was the only one unable to download 5.6 !!
I have tried the following servers with no luck in downloading 5.6.
Amsterdam, The Netherlands
San Jose, CA
Strangely at the time of writing this I notice that Source Forge is stating that there have been 7024 downloads of Eraser 5.6 !!!
Has anyone actually been able to download Eraser 5.6 from Source Forge and if so how ! :lol:
