Check for a stable and reliable connection. Bad connections can cause time-out and improper downloading of the certificate.
If stability and reliability is suspect contact your ISP.
If you are using a firewall or anti-virus software you will need to set them to
recognize and trust the application. Connection problems caused by firewalls
are most likely when you first run and after you update to a new version.
The easiest way to fix this is to go to the firewall permissions and remove all
references to application and let the firewall prompt/relearn.
Also be sure you are only running one firewall at a time. Two or more firewalls
will conflict with each other and can cause connection problems.
If your software firewall has the application added to its exception list, the other
possibility is that your router has a firewall blocking the application. This
has been seen with some D-Link routers.
Additional help on setting specific firewalls can be found at the following webpage:

bandwidth and can cause time-outs and connection problems. These should be
paused or turned off when the application starts if they are suspected.
