Meteor slides disappeared

Hi there,

I updated my wordpress yesterday to 4.1. Now I have no slides tab, no slides and the slide show on my homepage is simply a white block

Unfortunately I am not even close to be a beginner on this but I tried to reinstall meteor slides plug in and it says it already exists but is not in my installed plugins (active or otherwise).

Can someone help???
Thanks
Libby
