"Cannot Locate Reverb Impluse Response File" C13 Pro

I see this topic for older versions but have not found a solution. I get this notice and similar ones for reverbs and guitar amps. A few months ago I began using a Mac Studio M1 after working for a long time on an old Macbook Pro. At the same time I updated from Cubase 12 to Cubase 13. All was well for a month or two, but now I run into those notices on projects that are continuing on the new system. In fact Reverence on a project from last year is completely non-functional. I welcome any help to straighten this out, thanks!

Hi,

Did you install the whole library, please?

As far as I know. What part of the library is especially needed for this?

MOSTLY SOLVED
I am not sure still what led to the issues, but I re-installed Cubase 13 Pro 13.0.41 and (almost) all the functions are happy again. So far, the one item that is odd are tin he projects in which I used REVerence. After the new install, the REVerence plugs remained inoperative, so I dumped them and loaded new instances, restoring the settings by memory.
