ok so i had the trial version of nero 7 premium, which i really like, and when the trial period ran out i tried to uninstall it to install the full version. midway through the uninstall wizard it slows the fuck down to a crawl. when i cancelled it nero stopped working. now it's stuck halfway uninstalled and when i go to uninstall it, it shows me an error screen. i cant install the new one till the old one is gone, and i cant uninstall the old one. any answers?
