Hi,
I don't work at Acyba, so I can't check for valid licenses. Your screenshot from Acymailing says your licence is expired. Normally that's easy to fix. By the way, I also wrote that I'm not sure if the issue was related to an expired license.
First click in Acymailing on the refresh icon next to the version number. If that doesn't fix the issue download Acymailing from Acyba's website again and install it again. Normally your license issue should be solved.
Since you have a valid license you're also entitled to personal mail support. If you can't fix the two issues please raise a support ticket as described before.
