In that case I am curious what does make the tabel, because it isn't in my 3.8.8 database....
Anyway, whatever creates or updates that database, does not set all refcounts and width and height fields, but in my case only the last 34. And I am able to reprodues that over and over again by upgrading the database from 3.8.8 to 4.2.3
This because vB support just told me that doing the upgrade again would fix my problem, not telling that the Refcount and cleanup job were the actual problem.

Lets hope it fixes the missing height and width fields as well, because, then though I have my attachments back, they do not show up in the messages itself, due to the missing height and width data. vB support confirmed that the missing height and width data is the cause of that problem. Unfortunately they were not able to supply a fix for it.
