@Anonymous User Welcome to the forum. Just to check, on the website if you go to your My Account >My Passes page
http://account.nowtv.com/passes
do you see your trials showing as active?
If so, go to your My Account > Account Details page http://account.nowtv.com/account-details and check what username you are logged in as. If your password contains any special characters it might also be worth changing to one with just letters and numbers.
Then make sure you are using this username and password when signing into your LG TV app. If you still have no luck try popping onto live chat, explaining what's happened and see if they can help. You can get to live chat from the Contact Us page

(expand the Anything Else section at the bottom for options)
I'll also tag @commanda6 who is an LG app user, he may have some extra thoughts.
