You can use ZenMate (add-on for internet browsers) to change your IP, dl Stars 'from Germany' for example and play normally with your Latvian IP. Obviously don't use a VPN while playing, it's forbidden and not necessary.
You can use a VPN to dl P*, then play normally. ISPs are blocking the site, not the client. Got this e-mail from P* in September :
Hello [xxx],
Thank you for your email.
We are aware of the fact that some local internet service providers may be blocking access to foreign gaming websites and we are currently analysing what can be done about it.
We can assure you that your funds are safe with us and that you will be able to play normally if you download the client from one of the following links. In case you are using another device, I have added different links:
. Windows: http://tbf.me/a/4J8yp
. MAC: http://tbf.me/a/tyCf9
. Android: http://tbf.me/a/5NGRR
If there is anything else we can help you with please do not hesitate to contact us. Have a good day!
Regards,
Edurne

If you use ZenMate you won't need the links I sent you (I have never used them).
