Sorry, somehow missed your post! A better pic would be good but lets have a go anyway.
From what I can see it looks like you've damaged a lot of the half-pads that should be linked to the diodes - the red, pink and blue dot pairs should have continuity, if they don't you'll need to solder a jumper wire from the switch pin to the end of the diode. Why the diodes are so small I don't know, that will make it harder
That might fix it but if not the XD75 is a community DIY PCB which means it's sane so there should be continuity running up the columns, like the yellow and green dots. If there isn't you'll need to solder jumpers to reconnect them.
