Version 1.21 of GoPlay has been released and can be downloaded from at http://downloads.eaxia.com/SetupGoPlay121.exe. While all Windows users can use this version, prior versions are incompatible with Windows Vista, so Vista users should definitely upgrade.
Please note, in the installer, use the "Repair" option, or uninstall the application and reinstall it, whichever you prefer. The "Modify" option will -not- upgrade your version of GoPlay.
