Windows, and I downloaded the public build. But now I've altered it and whenever I un-download and re-download, and now it opens with word or something?
I really don't understand computers and hope that this gives some infromation
It's okay. Delete whatever you downloaded. Download the public build again, then in your downloads folder -> Right click the file and look for 'extract' or 'zip' or '7zip' or something like that. Then find 'extract here...' or where ever you want it, then in the extracted file look for Tamer.exe (the one with the picture), click that and you should be playing
