I got my SQ-A today and I have a couple of issues for the experts. When I first assembled the kit I had no problems with the dark slid but now it won't go in. It's as though there's some sort of lockout like a pin or something obstructing the gate. Anyone have any idea what's going on? Secondly, I got the grip but the two little nubs that rotate when you cock the lever are too short to engage with the mechanism on the camera body. Do I have some version that's for a different variant than the SQ-A or is something missing from the ends of the nubs that give them the reach they require? I'm kinda stuck with these two issues. I have an SQ-A manual and it addresses neither of them.
