Failure to Launch eM Application

I have been using eM Client for about 8 months now and never had an issues. Yesterday I accidentally closed eM while it was sending a message. So I tried to open the eM shortcut to resend the message, and now I can just click and click the short cut and eM will not open/run. I uninstalled and reinstalled and still nothing. Any thoughts? eM was my only tool into my company email and I need to figure something out soon.

does it display some error? Can you find eM Client process (MailClient.exe) in Windows Task Manager?
