Good morning Samuel and Marcellin,
I was not able to, because of the necessary permission to open the main v3 db.
However, the St.Vincent main v2 was accessible (able to open).
So an attempt to upload data from St.Vincent main v2 to main v3 (using main MS access and v2 as source) was the next step- but no progress. The preparing to upload took very long with no visible activity.
Following Samuel's steps nonetheless, the Compact and Repair Database was done for main v3 db and intermediate db from access in that order. The upload to main was attempted again without success.
