Just noticed Session Drummer has disappeared from my computer...What to do?

I've been involved in yucky life changes and haven't spent much time enjoying all the new changes.... but tonight I was trying to consolidate/cleanup/organize my vsts into a main folder (they were in several places,) and while organizing my plugin folders I noticed no Session Drummer! Searched computer, no luck... still have 8.5, x1 and x2 on computer so don't know what I may have done... Do I need to reinstall X2 to retrieve it or anyone have any thoughts? I assume it's still there somewhere but not knowing the exact search term, I may have missied it.... Maybe time for a clean reinstall with new sd drive, but figured I'm just missing something easy....

Thanks in advance!
