Unfortunately due to a bit of bad programming, the Group systems allow
for improper names for groups and someone created a nameless group.
When the group was deleted, it deleted all the GroupVPN data ...
fortunately it was just certificates, but that means all CAs are lost
except for groups created prior to May 2010. You can verify by
downloading a groupvpn configuration file and if it contains a cacert,
you are fine. For other groups, there are two solutions:
1) create a new group
2) I will add a button "generate new CA" (I will post when this is
available)
The latter will keep all your members but all users will need to
redeploy their groupvpn config files.
My sincerest apologies for the inconvenience.
