Some of my synths will upload, others won't. I am logged in to my Windows live account, and I've checked online on my computer to see if my windows live account is indeed functional... and, it is. So select one of the problematic synths, select 'Share', then select 'photosynth.net', give the synth a name and a thumbnail, allow it to be public on photosynth.net and bing maps, and then click upload; the result is a message that says "Uploading to Photosynth.net, view current downloads", but the message eventually goes away and I'm left with a synth that hasn't uploaded. Again, this only happens with some synths and not others. Any help?
