That pretty much explains it. Downloaded it twice, opened it, entered my info, it downloaded registration stuff, then told me to click FINISH. Then it closed, and wouldn't open again. I uninstalled, reinstalled, uninstalled, redownloaded install, reinstalled, uninstalled, downloaded from another name (sdcentral_gc2_setup.exe vs. sdcentral_setup.exe) same problem every time. Uninstalled, deleted install file, rebooted, redownloaded install file, reinstalled, reentered info, same problem. Suffice to say I am incredibly frustrated with this software.
