LVT flooring section by section

[proxybon]

Hi,
Disclaimer - I'm a diy enthusiastic for obvious reasons.

I started my lvt quick step click flooring in 2 section n now stuck

Since our kitchen n lounge was big and I had to do the underfloor heating so I decided to do it in portions.

Problem is the lvt click is not happening it's very very difficult to get it in...
Should I remove everything n do again or is there any other options.

Appreciate any advice or guidance

Thanks
