Error when using RTFX pack - says used on 3 computers but only used on 1 pc

So I purchased the RTFX pack a while ago and have been using it on After effects. Recently I re-subbed to adobe after effects and when I try to install RTFX its says cannot you have already used on 3 devices. I have only used the license on 1 pc. I am not sure what I need to do to continue using RTFX.
