Can't login to admin console

I have just installed iSymphony and activated the iSymphony module. With my FreePBX full-admin account I can login to the iSymphony web client, but I can’t login to the Administration page of iSymphony.

Again, I am using a full-admin account (FreePBX->User Management->Edit User->FreePBX Administration GUI->Grant Full Administration Rights: Yes). The iSymphony module should be syncing my admin account in FreePBX to an admin account in iSymphony, yes?
