First of all, you shouldn't refresh the vote rewards page while the countdown is working, although is ready for it and the countdown will continue counting.
I reccomend to not vote more than one vote site at the same time, although it work, you have only 3 mins to vote and sometimes vote sites last a bit to take on account your vote.
If on L2Topzone says "Time up! We couldn't process your vote at L2TopZone." is because your vote didn't count, maybe you voted today already or I don't know, but just the vote was not taken into account, is not our fault, its just a L2TopZone thing. I reccomend to wait 24h before to vote again.
If GameSites200 says time up, probably you were too slow, or the vote is lasting a lot to take effect and 3min were not enough. I reccomend to reload the vote rewards page and vote again or if you already voted for sure, just click the link and wait 3min more without voting again. If after reloading the vote rewards page says you already voted and no give you the aproximated time, I'm very sorry, you lost the points, we'll try to improving the vote system to avoid this, maybe giving more time than 3 minutes.
if Top100Arena says time up and you are sure you voted, don't worry, Top100Arena will always reward you with vote points if was sucessful, even if you shut down your PC after vote, they notify our server when a user voted successfully and we give the reward.
If Gamesites200 or Top100Arena says you already voted is because your IP already did it 100% sure since those vote sites recoginize if your IP voted unlike L2Topzone that we only say that your ip voted when your vote was taken into account and you got the points.
If the vote rewards says the aproximately time internaly means that your vote has been counted by the system and you got the points 100% sure excluding Gamesites200, that maybe you did't got the points.
About what Sekai said, I think the vote system is operating at 100%.
@Muuzyk is very weird what you say, because all tops say your aproximately time and this means you got the points but Gamesites200.
I hope this info helps you.
Regards.
