Some time ago I had no problem to betting from uk, now Im getting like this :
Unfortunately, we can not accept bets from your jurisdiction, sorry.
Im not sure what do you mean by " some time ago " but it has been atleast a month since they decided to close their service to UK based player ( references below ). However a simple VPN / hola could solve this or simply ask a non UK player to set up a bet that you want, you will then only need to send your wager to the corresponding bet address
The UK Gambling Commission has written to online sportsbooks, bookmakers and casinos telling them to block anyone with a UK IP address.
Already, Direct Bet and the Fairlay Bitcoin betting exchange have implemented this today.
It's outrageous.
