langover stopped working

i have been using langover for a long long time now, never had an issue with it.
but suddenly, it stopped working.
the icon is gone from system tray, and when i re-launch the program, nothing happens.i have checked task manager and langover.exe is running for a few seconds, and then dissapear.
re-installing did not help either.in the past, when install has finished, the program will start with a splash "setup" to instruct the usage of the program.but this time, nothing happend.

So, i tried reinstalling it following this procedure:
1.uninstall.
2.reboot.
3.download latest version and install.
4.reboot.
and still, it does not work.

i even tried a methood i have seen here, deleting langover.com folder from users... directory.but nothing seems to work.

i'm using windows 8(not 8.1) x64, and have been using langover with it for a long time with no problem. i happend just suddenly.
is there going to be a fix or a new version?
i really need this program and there is no alternative to it.

I have the same problem on windows 7.
Ironically it stopped working immediately after submitting my contribution.
Already tried to uninstall - re-install.
Can I get my support back?
