SRL Archive - Help

I've download Simba on windows 7 64-bit and then enabled the extensions. But when i check for updates for MSI, SRL, and Reflection it comes up as error and dosn't allow me to download the updates, whats wrong?

Does http://wizzup.org/static/srl/srlref.tar.bz2 load for you? And what specific error does it give (can't help much if you say "an error" without giving what the error said! ;))
