Get your taxes done using TurboTax

@garycoryer

Exactly. External drives are added and removed from systems all the time. That's what they are designed to do. No team of professional developers would use ephemeral external devices as part of the system fingerprint for software activation, so that speaks volumes about the lack of professionalism with this product. It makes me very concerned that I have been relying on their tax calculations when they can't/won't even fix a major bug that keeps deactivating valid installations. Based on various comments in other threads, it appears that no one has bothered to fix the problem in more than a year.
