Did the leaves fall off? Something not working right? Let us know how we can improve the Photosynth experience.
I cannot open the photosynth program, when I click it it says "Photosynth service not available. Please try again later." I've tried to uninstall and reinstall it, still no luck.
What is happening is that on your computer something is interfering with the Photosynth program accessing the internet.
Try checking your firewall's settings and making sure that Photosynth is allowed internet access.
