See attached screenshot. Your "new" Feb-2019 key worked fine!
I have copy and pasted the key (valid until 2019!) from your original
registration email into an ASCII text file and sent it to you one minute
ago.
When you start the sb100_5995_dev.exe, paste the Feb-2019 key into the
maintenance key dialog.
Does this work now?
