How to get Triac LTspice sim working?

[Flyback]

Hi,
Do you know how to get the attached triac sim working in LTspice?
I linked in the triac and diac library from st.com spice model which i downloaded.

I was working off this...

LTspice: Learn How to Use a Triac in LTspice Electronic Circuit Simulator Computer Software

Simulating a TRIAC or DIAC in LTspice can be a challenge as these parts do not work straight out of the box. This video shows you how to get the job done.

What feature doesn't 'work'?

It doesnt recognise the subcircuit, even though i made all the pins correspond, and have the subckt in the schematic now.

I wondered if the .asy file has to be called DIAC.asy, or DB3G1.asy.

i actually think ive messed up the symbol file now, and may have to reload LTspice completely.
