I was one of the first people to buy Start8. I remember clearly the website said I could use it on all my machines - this is personal only not business use. I have 5 machines, Two each at two houses plus a laptop for travel. Everything has been great until V1.45 and I have recommended the product to dozens of people. I am a good customer.
Now I installed 1,45 on two or three machines but on the next it refuses to accept the licence saying it is registered to another machine. I now see references here to it being allowed only on one machine or perhaps two.
So you have changed the rules and presumably rewritten the EULA.
I have reinstalled 1.41 and it is working again. But now I'm worried the other machines with 1.45 will start going wrong.
YOU HAVE WASTED MY TIME AND MESSED UP MY COMPUTERS AND THAT IS HARD TO FORGIVE.
Please sort out your mess, return to the previous rules and system, and make an apology to your users. That is your best way forward.
