Front tire skidding, resulted in a crash, any advice?
I currently ride on Rubino Pro Slick tires, and have used various Vittoria tires for decades.

The Vittoria Rubino tires you are using have similar wet grip to what I use (dry grip will be the same). The pressures you quote are good. 

I get the impression that both incidents occurred in the same corner. If that is the case then I would strongly suspect oil on the road.

When cornering with under inflated tires, they give a characteristic sickening lurch to the side, usually accompanied by a scrubbing noise, and then they let go. This kind of crash can rob your confidence. Just take it easy, be extremely careful on that corner (or avoid it), and get well soon.
