Remote access - certificate expired/security warnings

Trying to access files online using W2go.com.  My password is accepted but I then get a message that states “application blocked by security settings”.  Your security settings have blocked an application signed with an expxired or not-yet-valid certificate from running.

How do I fix this, if it is fixable?  

is there another way to access my WD device online other than using W2go.com?
