interesting. mastodon.el also uses plstore, so if it works (saving your credentials) your machine's encryption should be working. but the auth process for the two services is totally different, so I had to write the lem.el auth code from scratch. I can take a look at it v soon, I'm keen to have any auth issues sorted out asap.
it'd help if you cd describe when the error message appears, or what exactly you do that causes it.
actually a backtrace would be most useful to track down the error.
you cd also try opening the plstore file in your .Emacs.d folder and encrypting / decrypting it.
thanks!
feel free to message me or to open an issue on the repo if you run into issues getting lem.el going. others have already helped me iron out a few getting-started issues.
