[lubuntu] problems launching davmail in 64 bits ubuntu 12.04

Hi everybody, recently I have downloaded the davmail package: davmail_4.3.4-2174-1 _all.deb, I installed it using ubuntu software center, and also davmail icon can bee seen in my launcher, but when i try launching davmail console i was unable to use it, I uninstalled and re-installing the program even using the command sudo apt-get purge davmail, but as soon as this one has been installed again and after my laptop is restarted I try to launch again but the console is still hidden.

Can anyone help me please?
Could you tell me any idea?

thanks!!!
