This mod doesn't change your database or contain any custom install code at all, it's highly unlikely this mod caused your issues. You might have had a sever error in the middle of the uninstall unrelated to this mod, hard to know for sure.
To manually Uninstall go to the Admin CP, Plugin Manager... Find the section
Forum Goals by BOP5 there should be 3 plugins listed, delete each one manually.
Then go to your styles and template manager, find the template
forumgoals and
delete that too.
There are several phrases too but they won't hurt anything... If you really want to delete go to your Phrase Manager, find and delete the following phrases:
- bop5goal
- bop5goalreached
- bop5goals
- bop5posts
- bop5poststogoal
- bop5threads
- bop5threadstogoal
- bopdaystogoal
- bopgoaldate
- bopovertime
That's it... that will remove all traces of this mod. You can also try to uninstall it again if it's still listed in your product manager.
If you can't get to your admin cp follow the instructions to disable hooks first:

That should get you back in the system.
