When any new version of any operating system is introduced there are inevitably bugs. Unfortunately Lab.gruppen does not have advanced access to new operating systems to test ahead of the release.
Windows 8 has been known to cause problems when using with our Lake Controller Software.
The best way to get around these issues is to turn off all programs which may be running in the background. Turn off Anti Virus, turn off your firewall, turn off any background programs that may be running and you should find that Lake Controller runs just fine.
