[lnhrdt]

@kwinH, @BerndWessels, and @treasureDouDou thanks for reporting this issue. Apologies it has taken me so long to reply.

I believe this is related to #4 and the underlying issue that the code I wrote didn't work properly on Windows systems. I had only tested it on *nix systems. A fix has been merged to master. Please try to tool again and let me know if you have any further problems.

I'm confident the cause of @kwinH's issue was resolved based on his logs. If I'm wrong or you have any other problems please reopen this issue or submit another.
