TekkitLite update problem.

[Chlorek]

Hi, I was playing TekkitLite 0.5.6, I found that there is TekkitLite 0.5.7 available, so I downloaded it and while installing I got an error "Update failed!" in a little pop-up window. I looked to the log file to see this:

Moreover, it's werid, because when I try to download and install any older version (including 0.5.6 that was working before), I see this error all the time!

I am using Java 7u13 64bit (latest). I have also 32bit version for my webbrowser. What's going on? Please, help.
