Not that I can find, and I have spent a very, very long time looking. This program isn't sketchy though, VPN are services that have been established for awhile. And whateverfrog that runs vpyr is pretty well known (meaning they aren't likely to steal from you). you WILL have to cancel your subscription tho BEFORE the 3 day free trial is up (they have a link on their site how you can do that) unless your like me and you only have 2 dollars in your bank account (I have it set not to be able to take overdraft fees) so it will get cancelled as soon as they can't take the 6-8 dollars or whatever to keep it running. Riot usually has the issue fixed by 3 days anyhow (yes this has happened before).
If they havnt you can decide whether this game is worth a 6-8dollar a month con program to run or not (how much do you enjoy lol that is).
The thing about this fix, unlike other fixes (the press enter after 5sec, the restart lol/router, change wifi from wpa/wpa2 to wep), this is the only solution that works for EVERYONE (so far) consistently. Although I do recommend trying the others first.
Good luck
