check your firewall settings... try nyo din restore default yung firewall nyo.. another option download XTRAP file sa Tantra website tapos extract nyo sa folder ng tantra nyo.. tapos pag may nag pop-up na question sa WINDOWS SECURITY or FIREWALL SECURITY.. ALLOW ACCESS nyo.. or UNBLOCK... isa pa din factor is CONFLICT yung XTRAP sa ibang anti-virus or simply register nyo sa Exemption yung XTRAP ng TANTRA CLIENT nyo!
hope this will help you! thanks...
