I got a lot of errors downloading the latest catalogues and packages with the mingw-get-inst using the default download uri "http://prdownloads.sourceforge.net/mingw/%F?download"
If i change the uri in the profile.xml file to "http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/mingw-get/catalogue/%F.xml.lzma/download" all catalogues download well.
But the problem is the same with the rest of xml packages, i have to change manually the uris of all to get them working and download.
I got always at least 30% of download errors from the default uri. My internet connection is OK, and i have tested it without firewall and anti-virus.
This problem is not puntual, it's happends always to me.
Thanks for your work and excuse my poor english :)
