[MlMt] Rebuilding cache

[Henry Seiden]

Martin,

I’m at a loss. There might be clues in that error…

The settings folder I referred to restoring from your backup (be sure   close the app first) would be everything in *~/Library/Application Support/MailMate/*

Seems you only attempted a restore of Messages folder? Maybe another opinion is needed on this. Ask Benny.

Personally, I have not had this situation, but have restored my settings (not Messages) in the past with success. There is a process for this in the MM Help menu and MM Manual.

Respectfully,

Henry Seiden

After restoring, I found that MailMate crashed repeatedly and consistently shortly after I launched it. I tried rebooting the computer, but this didn’t help. However, after about maybe twenty relaunches of MailMate the problem went away. Except…
