Your issue would seem to be this below
1. Your admin is not usergroup 6 which is vb admin usergroup
I was going to say your usergroups entries maybe possibly where not imported from VB but they would have to be as your logged in
View your photopost usergroups table and set cpaccess to whatever usergroup that user is in.
Usergroup 6 should have a cpaccess of 1 already set at least we set it to 1 on a new install
