I tried to download the preview from sourceforge and got this msg"
You are requesting file: /alfresco/alfresco-sdk-1.3.0dev.zip There was a problem downloading the file from superb-east.dl.sourceforge.net. Please try a different mirror.
I tried several mirrors all with similar msgs. Has it not replicated yet? It says there's been 836 downloads. Does sourceforge count clicks or completed downloads?
