do i have an outdated version or something? please help cuz i wanna add some things to my game

have you tried reinstalling it?

If you think it's outdated, you should install the new version.
Or ask people for help in discord. Both will "maybe work"

First of all, try re-running the installation process.
If this doesn't work, see if it has any updates available (the client has changed quite a bit since I last logged onto the site).
If you still have issues, contact help@brick-hill.com for advice.
