Help

I Can't get Calibre to run. I have no idea why it won't run as it was up and running this morning. Hope someone can help me. It won't open at all. I have uninstalled and re-installed, making sure that everything is removed in between. I click on it, the starting Calibre thing shows and then it won't open. Nothing I have tried has worked. I guess, if no one knows what else to do I might have to rest by pc to factory.
