elements 2019 wont render

[Team Robertson GB]

Been using Elements 2019 for a while now on the same laptop..... But

It wont render. The button click as such, but nothing happens. Ive tried the fault fixes on elements20, but that doesnt fix this. 

Help.... Before I throw it all in the bin. 

Im running Win10 to the latest updates

Run Norton Security Ultra.

Other videos have been fine, but i had to delete my last video as its as if i over cooked whatthe device could manage. From that point onwards my laptop has been very very slow. 

** This is my first post, so be gentle if ive missed something imortant or technical **

I would turn off Norton and just use Windows Defender which is quite reliable.

Virusscanners have a habit of slowing things down.

Do you have segments of your timeline that require rendering (as indicated with yellow-orange along the top of the timeline)?

Have you ensured that the Work Area Bar is over the segment you want to render?

Can you post a screen capture of your timeline so we can see what's going on?
