I recently had a failure in sending/receiving emails in TB 102.2.2 on my Win10-64 machine. After much help from my email provider, sending/receiving worked [sending/receiving provider addresses got messed up somehow]. However, my address book then failed to show any addresses; the address book opened but was blank. Looking in the appropriate directory showed several "abook. sqlite" files of various vintages, all seemingly populated as indicated by large file sizes. Tried all sorts of things following HELP suggestions but nothing worked. Tried reinstalling program. All "solutions" had empty address books even though file sizes suggested otherwise. Problem: how to access my personal address book [or any address book for that matter] from within TB. Thanks in advance for any and all help.
