Photon M7 WaterWashable resin not sticking to plate

Hi, it's my first 3d printer and i find myself with a bit of a issue. I tried printing the RERF file without using anything else other than pressing print and went fine.
Now that i adjusted the slice parameter to fit AnyCubic default for Water-Washable 2.0, i failed my next prints, with no items that sticked to the plate.
What can i do to fix it?
