DMS pro tools no more exists?

[dgdeeper 4]

Im trying to add some sections on brand new web site but DMS says they are only available with PRO subscription. 

Such sections as flipper etc. I have a DMS activation key but I can't see where should I paste it. On my previous site i've installed dms pro tools, but on the new one I can't see this feature anymore.

You need the updater, thats where the key goes.

Should be in your account area.

Hi
Just updated Wordfence to Premium and ran a scan. It says: The Plugin "DMS Pro Tools" appears to be abandoned (updated June 1, 2015, tested to WP 4.1).

Should I delete this plugin? If so, will that break something on the site? Site was built with Whitehouse theme, DMS2 is also installed

also get this error: The Plugin "DMS Dev Tools" appears to be abandoned (updated January 20, 2015, tested to WP 4.1).

Please advise if Pro and Dev Tools can cause problems with WP more modern than 4.1???  thanks

Ok, now I also see: The Plugin "PageLines Updater" appears to be abandoned (updated August 5, 2015, tested to WP 4.1).
