Firstly, from what I can tell in your log you aren't actually running the latest version of Jaksta. We have just recently released Version 2 of Jaksta Media Recorder (formerly named Jaksta for Mac), which is a paid upgrade, but even then it looks as if you are running 1.4.6 when the latest 1X version we had was 1.5.1.
So first I would suggest installing V1.5.1 and seeing if that helps. You can get the installer here: http://download.shedworx.com/jaksta/beta/Jaksta-1.5.1.pkg
If the program is crashing on startup, then when it is reopened there should be an info window that pops up giving you some text and then 3 options - Reopen, Report and Ignore. If you get this notice, then click on Report and it should direct you to a crash log. If you can get that far, get a copy of the crash and attach it to your reply email.
