Error while updating getdown.jar itself

[Tomáš Růžička]

Hi,

I have a question about updating getdown.jar. Getdown (version 1.8.2) updates all files, but when attempting to update itself (replacing with earlier version - 1.8.1), it writes the error into the launcher.log and the "loading screen" continue to display (unable to close it). Here is error message from launcher.log:

After killing java process with task manager I'm able to launch app again without error.

Thank you Michael! I was reading "Anatomy of the getdown.txt file" many times and totaly forgot about the rest of the webpage.
