I know Raid is leaving fb, and have managed to get my account over to work using the plarium play launcher instead as it will be my only option by the end of the month.

As stated above, when I play using facebook, the game plays perfectly, no lag at all.  When I try to play through plarium play, the lag is so bad that the game is virtually unplayable.  I have reset the cache etc, but nothing has helped.

Why would this happen and is there any fix for it?  I really love the game and have spent a fair bit of money in the past year or so I've been playing. Any help would be appreciated.  I am in the UK and as far as I can see, playing on a UK server.  

Thanks in advance.
