karambaGH plug-in not found when Karamba3D is installed

My Grasshopper already had Karamba3D installed some time ago. Thought, I just got a file that I need to look at but the problem is, it said that I don’t have “karambaGH” plug-in on my Grasshopper, as you can see in the picture attached below:

Could someone help me solve this issue? Thank you very much!

Hi, try to uninstall your old versions of Karamba and then install the latest version. It seems that your definition contains components which are found in 1.15 and these components may be obselete now or replaced. The definition should open up if installed correctly and the components will show up as OLD
