can you attach a screenshot of the message, if it's in english?
that's a mac, not adobe error.
what do you see when you click report?
update your creative cloud app.
if that fails either, using a browser that allows popups and cookies, contact adobe support during pst business hours by clicking here and, when available, click 'still need help', http://helpx.adobe.com/x-productkb/global/service-ccm.html
uninstall everything cc including preferences, https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
then uninstall the cc desktop app, https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html
clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html
restart your computer (don't skip this)
reinstall the cc desktop app, https://creative.adobe.com/products/creative-cloud. (if you have a win os, right click the exe > click 'run as administrator'.
use the desktop app to install your cc programs/trials
Thanks, I'll give this a go
