I have version 1.3.3 (139)
Are you perhaps talking about Jaksta for Mac (now renamed as Jaksta Media Recorder)? Because that is very different to Jaksta Converter (which does not record at all - only converts), which is what you have posted this in.
If it is Jaksta for Mac and you are having recording/downloading issues, then I would guess that it is because you are running a very outdated version.
It would be best to start by updating to the latest build of Version 1 that we released before moving onto Version 2. You can get the installer here: http://download.shedworx.com/jaksta/beta/1.5.1_00/Jaksta-1.5.1.pkg
Once installed, there is a good chance you will receive upgrade prompts to Version 2, which is a PAID upgrade that we released earlier this year, but it is not mandatory. You can turn off the prompts by going to Preferences > General and turning off the feature that does auto-checks for updates on startup.
There is a discounted upgrade offer for existing license holders, which can be accessed by following the prompts in the update checker pop-up notification.
Please be aware that we will not be releasing any more updates for Version 1, as we are focusing our development on Version 2.
