PVP error

When I start the PVP, I get a popup saying "please relogin game" every few seconds, and I have to click restart. Anyone know what is wrong? I can't do anything in the PVP.

Thanks!

its just lag and a poor connectiion

Everyone keeps saying its just lag, but I tried for over an hour last night and this morning its the same thing. And now the lag improved so the message comes up faster now. Last night with the lag I could sometimes go into chat but now I get the message immediately after loggin in.
