Help me, I'm getting an error while trying to join the server:

the files "C:\program files (x86)\steam\steamapps\common\arma3\!workshop\@O&T Expansion Eden\addons\expeden.pbo" are not marked with an acceptable key from this server. To play on this server, remove the listed files or install additional compatible keys.

I tried unsubscribing and subscribing again to O&T Expansion Eden mod but it didn't fix that.
