I do not have RF8 (I have RF7.5 and RF-X) I imagine you have searched the RF8 settings options for program allow/disallow features.
Have you tried disabling anti-virus/malware programs and make sure RF8 is not blocked by your firewall.
Try updating system drivers, if all okay then re-install RF8 would be next step.
