No longer working for me anyway.
I'm not a whizz in the technical department but I understand there's been a change to Adobe Flash player, as in, Adobe no longer supports Flash. I think it ended on the 12th January.
Was the NMP Site using this program as none of the games seem to work anymore.
I've checked my side and can still get games from other Sites, so it's something to maybe look into.

I know we are in the middle of a pandemic but the games could be useful for people in lockdown.
I understand if it's not priority though. Thank you.
