Plugin - Not letting us use pro features

Hello,

We recently re-added the plugin files to our website - robertholden.org and paid for a 3 month agreement and for some reason I am unable to change any of the settings within the newsletter pop up we created.
I have tried to create new pop ups but the plugin does not allow me name the pop up or save any attributes. Per (from Predrag Dubajic) we were told we can download the plugin from link provided (https://premium.wpmudev.org/project/the-pop-over-plugin/) and just overwrite the old files via FTP, and all our current settings will stay there since they are being saved in our DB - but after we did this we were still unable to use premium features. Please help.

Thanks,
Kate
