We've just changed our server to one advertised on the Paltalk clicky things, and now I can't get any sound.

I've tried doing everything they told me, to the extent that I've re-installed it twice now, and still no sound. The volume is up, the mutes are off, but still not a dicky bird.... can anyone help me, please??

LTS, who has already changed her Paltalk cookie once and is starting to get annoyed!
