I have had this issue for 3 years now, on all versions of the Xen versions since available. After installation, it will work for a week or 2, then will stop working. I can see all the applications I have access to, but when I try to launch any (in either online or web client) nothing happens. If I logout of my laptop, then login as a different profile, it'll work.
The only way I can get it working again is to uninstall, delete local folders and manually go into the registry and delete the keys under the current user (for some reason the uninstall does not remove the keys and unless they are deleted re-installing won't fix the issue), re-install, log off, log back in and I'm working again.
This becomes such a pain and have not been able to get any solutions other than my workaround of re-installing. I am an administrator on my laptop.
