Mail me on gmail (same user as the one I'm using now) with a screen cap of the purchase invoice, and I'll send you an alternative link.
I waited for the mega cooldown and downloaded the khan-0.10.9 market zip folder but there is no exe in there? Am I missing it or did I download the wrong folder?
It should be in \Khan-0.10.9-market\Khan.exe. I also mailed you a Gdrive link. LMK if you still have problems.
