I clicked this link today and it told me that I have already done it and that multiple voting is not allowed. But I have not already done it and this is the first time I have been on this weekend. Does this have something to do with the fact that I never got credited for the first time that I completed a weekend promotion?
Payment for the latest contest, Money Phrases, has not yet been paid out. So you should be OK, just keep checking here for the next one or in your account for payment. It is possible that you never got credit before if you did not get any answers right. If the link said you had already done the current one, then you somehow did it, or it's expired. It says the same for me, but I know that I did actually do it, however I can't remember any of the questions haha. Anyway, good luck!
