You really shouldn't be surprised when old plugins don't work. Not only has mybb changed since this plugin was last updated - but php versions as well. Possibly database software - but haven't tried with this one. You can argue it shouldn't be in the extend section, but I think that's more of a resource issue. And a conversation for another day.
Good rule of thumb - always be aware of when a plugin was last updated, and moderate your expectations accordingly. Might be more trouble than it's worth. Oh yeah - good idea to have a test environment to experiment and the means of quick rollback and recovery.
In this case, you can create a new group and grant them customized access to the ACP to activate users. Even keep the appearance of their current user title. All within the core system. I've done exactly that when the necessity arose.
If you need a more guided experience - I'd bite the bullet and go with a paid solution. Open source is not for everyone.
