After starting Creative Cloud just a white Window appears, no Apps or something else Windows 8.1, more uninstallation and re-install didn't bring a solution. I have had installed Photoshop CC Trial Version, but had to re-boot the system, so I lost the Software. After re-installing the Creative Cloud Desktop appeared just a White window. I tried to delete the file of OOBD in AppData but no reaction. It still appears as a clear window.
