This should be in the beginners' section, also upvoting a downvote:
if you pressed '-', you '-' it back and '+'. I hope I understood your issue properly
EDIT:
How do I upvote and downvote?
Click '-' to downvote and '+' to upvote. They should be somewhere around the top right corner of a message of forum user that you want to upvote or downvote, also what CrazyCrackers said:
You should be able to just click the + or - as I've shown in this picture. You used to have to make 20 posts before you could + or - posts. But since you don't have the "crpg player" tag under your name, that may be it as well.
