Wow... we burned through a couple of bug fix releases in no time! Let's give v0.10.5h a try, shall we?
I was getting a lot of support questions because folks werent granting network access to Slice Master. Now, Slice Master tries to verify the firewall rules and issue a warning if things dont look right. I'm guessing the problem shown above is due to a localization error on my part. v0.10.5h might give a false positive on the warning but wont stop Slice Master from starting.
