emClient Crashing and not working

Over the last few days my emClient has failed to work properly.
A couple of days ago I had a PC crash and it is the only program that has been upset by that.

When it came back on line it was checking the DB. That was fine. After a few hours I noticed that the icon on the task bar, where it was running, did not bring to the front the app. No matter what I did I could not move pass the icon. So eventually I had to end task again

Then it came up, checked the DB and seemed to work. That was last night and the PC has been on all night. This mornig it was frozen and no matter what I did would ot interact so I had to end process again.

It came back, did a DB check now I have the icon that suggests it is open but no app showing again. If I click on the icon my PC boings. I can also right mouse click on the icon and get the pop up menu but no app.

How do I resolve this. I have downloaded Mailbird so that I can continue to work. I do have Outlook but finding Outlook Classic troublesome these days

Thanks
