Hello Spicy ape,
Sorry you are having trouble. What happens when you run Spine? Does a window appear? What OS are you using? Does Spine show up in Task Manager (if you are on Windows)? If you are on OS X, please try closing other apps, as some applications interfere with Spine. Please post your spine.log file, if one is created:
Windows: <user home folder>\Spine\spine.log
Mac: <user home folder>/Library/Application Support/Spine/spine.log
Linux: <user home folder>/.spine/spine.log
We also recently released a new version of Spine. To use it, you need to go to your license page and download the installer again, then re-install Spine.
You should be able to find this link in the mail we sent you when you purchased Spine.
Write us to contact@esotericsoftware.com if you are unable to retrieve the mail or the link.
If this step doesn't solve your problem, it would be useful to have more details about what happens exactly when you try to run it by posting the logs.
