Mailmate keeps crashing

Sorry to hear that. Do you allow MailMate to send crash reports? (See the General prefs pane if you have time for that.)

I located some crash reports which indicate that the problem might be some kind of database corruption. Could you open a Terminal window and launch MailMate like this:

/Applications/MailMate.app/Contents/MacOS/MailMate

That should show an error before the crash.

It's likely the only workaround is to force the accounts to re-synchronize, but first let me know what you get from the above.

Sorry about the inconvenience.

Hi Benny,

I cannot change the preferences because the app does not stay open long enough.

Here is the info that appeared when I used terminal to activate MM.
It also generated an error report this time.
Both files are attached.

Thanks!
Mathieu

I'm afraid you need to re-synchronize MailMate completely. To avoid setting up your settings again I recommend doing it by removing the following folders:

~/Library/Application Support/MailMate/Database.noindex
~/Library/Application Support/MailMate/Attachments
~/Library/Application Support/MailMate/Messages
~/Library/Application Support/MailMate/Messages.noindex

If you have enabled the custom location option for Spotlight (in the General preferences pane) then you might also have a Messages folder in a different location. You might want to keep a copy of the Messages folder until you are sure you are not missing any messages on the IMAP server.

Also delete any files starting with a . (period). These are hidden files and you can see them by entering:

~/Library/Application\ Support/MailMate/
ls -a

Finally, relaunch MailMate.

If you have any idea how this problem started then please let me know.

Sorry about the inconvenience of whatever caused this problem.
