I cannot replicate any of what you are reporting, see the attached screenshot.
The deicers placed in the wrong position seems to be a problem with the airplane deicing point so, first thing to try, RESET the airplane configuration in the GSX airplane configuration page and see if it fixes it.
Pink textures instead seems to be a problem of an incomplete installation, which cannot possibly happen if you just updated so, it might ( but I can't say for sure ) also caused by having exhausted VRAM, because of too high settings, especially AI traffic.
