Stuck in 1st gear! HELP what happened?

Took my car out for the first time since restoration. My first mile drive things went great.Came home washed car and took it up the lane again and shes locked in first. I don't have the hump in yet so I easily unhooked the rods ,shifter works but can't move the 1st gear shift hookup(which i believe is the highest and most forward one) on the tranny. I'm at a loss. I need your help!!!! WHAT HAPPENED...
