Which browser did you use, have tried both IE and Chrome, I created an account and when I now try to login, nothing happens no error message no nothing.
Did you contact them or did they contact you on here? It'll be in their interests to sort it out and fix the issue. I can log in fine on Chrome but doesn't mean it's fine for you.
Just signed up to Laka. Incase anyone else is interested in signing up here's my referral link. Gives both of us £25.
