After install/reg Instrument Coll., only Organ doesn't work

I purchased and registered the MPC Instrument Collection on my Live 2, V2.12.2, all the Instruments are registered and functional. Also Organ is registered, but it cannot be loaded! It is in the List and the Screengraphics for it is in the overview. If I select it, nothing appears. Plugin selection says <none>. All the other Instruments are ok. I deactivate, and reactivate Organ, but it din't help. What can I do? The internal space is about 50%, so, no memory full problem. Maybe it is a faulty download? But no error messages

Delete the file from the synths folder and re download it again, sounds like something corrupted during the download or the extraction

If that fails, delete everything from the synths folder and re download it all

Also, although you can queue the downloads, I’d suggest just doing one at a time

Fixed!
Yes! That's the fault. The installation target SSD vs SD probably got mixed up during the initial installation. Deleting and reinstalling on the SSD is answered with black screen and reset. Deleting and reinstalling partial on the SD fixes the fault. I'll probably have to take a closer look at this later so that I'm not permanently dependent on this SD.
Thanks a lot for helping!

Last words to let you know, if it is a Problem not only me:

The installation target SSD vs SD probably got mixed up during the initial installation. Main should be the SSD. Unregistering the organ-instrument, deleting from the synths folder and re download it again, registering new, reinstalling on the SSD in any order, is answered with black screen and reset. That's maybe a real issue with black screen.
Copying back the original files from synths-folder SD to synths-folder SSD accepted from System. Organ-Instrument is back. Luckyli I saved the original files from synth-organ-folder, where it wrongly installed bevor from the SD. But deregistering, download and register it again, doesn't work!

Thanks
