Tips on avoiding database check

I’ve been using EM Client for over a year and really like it, except for the times it freezes up and I have to shut it down. Then when I relaunch it, it goes into the database check saying it was shut down improperly. I takes 55 min to check the data.

I upgraded to the latest version recently, hoping it would be improved, but it still crashes and does the database check about 2x/week. I use it everyday quite a lot. 

How can I make this better? Is my Inbox or Sent Items too large? I do have many storage folders from years of Live Mail and Outlook Express before that. Is there anyway to reduce the 55 min for the data check or stop it from freezing? I do have 2 folders underneath my Inbox for Old Mail

Any suggestions?
