Cannot activate the VPN client software on windows 8

Hi,
I use the VPN client software to establish secure remote connections with my remote workers.
I reinstalled it after an uninstallation but now I could not go passed the activation step. This step brings up an error and I was able to attach an image so that I can get help on this. If anyone has encountered such an error please help me solve it soon.

Error: Activation Error 70: Internal error
Please retry the activation later
