Dear

I tried to download MS office pro 2013 but key i can not find 

Always error : timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding

I am talking about the 60 days trail only

Where are you downloading it from? If you need a trial key it will be with the download. 

Hi,

If you switch to another web browser, does this issue persist?

This issue sometimes can be temporary, now you can try again to check if the problem still exists.

If you are using IE, you can also try to clear the caches  and cookies to try again.
