Can't uninstall Sharepoint server 2010
I Uninstalled sharepoint foundation and language pack after that when I tried to uninstall sharepoitn server it won't.I just click uninstall and like the arrow change to load arrow but then nothing happens
I tried to reinstall foundation but I get this error `Trial edition are licensed editions of Sharepoint, Project server, and Office Web Apps products may not be installed on the same server.`

what should I do ? 

Thanks
