Cant download from Factorio mod menu, "Selected mod has no released version"

I have no idea what that means. As far as I know, the only part of releasing a mod is uploading it here. And it has a functioning version parameter, as it would not even load if it did not.

EDIT:
Are you trying to install it into 0.14? It is 0.15+ only.

Yeah, I didnt know that you can change the version via Steam Beta tab to "update" the game to a newer version. Wish the devs would change the error to say it needs a newer version of the game instead of this vague error.

I highly recommend going to 0.15, but a 0.14 world will not survive well, given the number of changes, in particular to research and power.
