If you shortcircuited it, that means you can reach the contacts This also means you can use a glue that is filled with silver. I have a similar tube, comes with a pencil and is meant for connections like these (i used it to unlock my Athlon XP processor ).
Mine is from bison, it's called electrical glue i believe or something similar.
Get a soldering gun and drop some solder into that hole. Make sure to fill it so the connections are restored. That may be the only way for the lead to stick. If it doesn't stick that way, :dunno: wut next.
If it makes a mess, get a copper mesh and put it on the solder and heat it. It will suck it all back up.
