[SOLVED] New Error notice in JEM when using acymailing update!

Hi, please test and send feedback. After updating to the latest acymailing, I get in JEM strange error notices, but the functions work. e.g. during adding a user as attending in FE and BE in attendingmanager:
0 - Call to undefined function acymailing_translation()

Can someone reproduce this? Please send feedback.

[I wrote this to acyba, but they want ftp access to my site. I don't want to give them this]

I got an answer from acyba to reload and reinstall the latest version. Now the error is gone!
The actual download seems without this problem.
