Hi John,
I understand your situation.
I also have to say how much I love the fact that every single software developer I know believes he can fix every software in a heartbeat, if only he can get to the source-code.
I call it the "MOTU-syndrom" (Master of the Universe).
It's great to work on the go, and I do that as well, with 2 USB ports on my laptop and an unpowered USB hub connected. Works well. I don't work while I walk, though, so I never bump into things.
A hardware key is the only working protection for niche products like ours, that's how we see it.
I will see what can be done. Please bear in mind that this is the first (!) complaint about this specific problem in more than 10 years with eLicenser.
Best,
Paul
