Installation failed (LS 3.0.2, Mac OS X 10.8.2, MBP Retina)

Hello Little Snitch team,

I have problems installing Little Snitch. Updating form 2 to 3.0.2 turns out in "Installation failed. Please open the Log to see details."
I saw this topic: viewtopic.php?f=1&t=8183 but it seems to be a different problem.

In the Log the error lines are:

[...]
INFO: *** Starting Services
INFO: Updating boot caches...
ERROR: Pre-linking the kernel failed!
ERROR: The following Kernel Extension is broken:
ERROR: Prelink failed for com.jmicron.driver.jmPeripheralDevice; aborting prelink.
ERROR: Please check whether an update is available for the software package
ERROR: containing this kernel extension or uninstall it.
ERROR: For more details, run the following command in a Terminal window:
ERROR: sudo kextcache -v 6 -update-volume /

The suggested command returns (last lines):

[...]
setting load address of jmPeripheralDevice.kext to 0xffffff7f8106b000
jmPeripheralDevice.kext - no dependency found for com.apple.kernel.libkern.
Prelink failed for com.jmicron.driver.jmPeripheralDevice; aborting prelink.
Failed to generate prelinked kernel.
Child process /usr/sbin/kextcache[2659] exited with status 71.
Error 107 rebuilding /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache.

I'm on Mac OS X 10.8.2, Mac Book Pro Retina with Gate Keeper disabled.
After the first error I tried to remove all the files manually (including the LaunchAgents and LaunchDaemons) but the result was the same. Tried rebooting - the same.
If you need some other information let me know.

Best Regards,

Konstantin Erokhin

PS: Love your App - hope to get it working soon!
