Nstalled Saphire twice and premiere pro is extremely laggy and doesn't work as it should

So I recently downloaded BorisFx’s Saphire plugin and by accident, I downloaded it again. now my premiere pro is extremely slow, crashes and I cant see any settings or toolbars. I uninstalled it and now I am trying to re install it again but now whenever it is done installing I get an error message and must retry. any help would be appreciated.
Im using the free trial but it should still work as it did before i installed the second version by accident
