I just downloaded and installed the trial version of LRT4 but does not work. I get the message "LRTIMELAPSE 4 QUIT UNEXPECTEDLY" I would like to know what is the problem?....

Thanks.

Are you on windows or mac?
I assume on Windows: make sure to uninstall everything related to java via your Control Panel in Windows, then install the appropriate java version from the link provided here: http://lrtimelapse.com/install - use the 64bit version on a 64bit system!
Try again.

I am using MAC OS 10.6.8 What should I do?....

Mac OS 10.6.8 is not supported anymore by LRTimelapse 4. You could install LRT3, you can download it from the download page, but it will only run, if you have a license (3 or 4).

Thanks for your answer, I will download version 3 but I have a question. I much is the license for this version?., I don't see the price, neither the link to paid for this version. Is it the same license for version 3 or 4?...

You would have to buy a license for 4, since licenses for 3 are not being sold anymore.

I am very intereted in installing LRTIMELAPSE on my MAC COMPUTER, but I am not sure if LRTIMELAPSE 4 works in my computer with MAC OS  10.8.5?....

It should work. Just download and install the free version from http://lrtimelapse.com/download and try it for yourself.
