Having an odd problem...I already went through all these steps a while ago, then got a new PC and am trying to re-install Frosty...however, I can't enter the encryption key for veilguard, because the actual box I can copy/paste it into is not there! It's like the pop-up needs to be resized because words are cut off and there is no text box, but there's no way to do that. Anyone have any advice? I dont want to play Veilguard without mods
