BM 3.8 run on NW 6.5 sp1. Upgraded from BM 3.6 NW 6.0.

We have never setup the VPN before and now have a need to. However when I go into iManager and try to add the server as a VPN server I get the " Error: The VPN Server was not added. The selected server is already configured as a VPN Server !" message. I can not figure out why it thinks it is already a VPN server. How do I remove whatever is causing this error?
