Help needed with Vaporesso Gemini RTA Build deck

[mentalghost]

Ok so after some cleaning up and taking wires off and changing cottons I have come across one of the terminals are lose to the point its fallen out. The screw has come out from under it and has wobbled out.

How does one fix this as it looks impossible to put screw back in place

Managed to get the screw back in but sadly other side went and now given up and since thrown in the bin. Vaporesso if you reading this you might want to make a build deck that allows you access to screws so that you can change everything on it. I have Since gone for a tornado rdta upto 6 coils totally interchangable deck and strip right down and even have replacement parts for everything. Shame as Gemini RTA is a kickass RTA now switched as no email support no refund or any replacement to emails. Guess want everyone's money
