We are really sorry that you have such a problem, but version 2.x can have problems, it's true.
There have been numerous changes in the online database over this period of time and version 3.x is fully adapted to them.
You are not supposed to buy the upgrade weekly - a major update is released approximately once a year, all minor updates (which are rather frequent) are free for our customers.
Moreover, being aware of this problem, we offer all our customers a 50% discount for the following upgrades. I don't know if you know about that.
If you want to upgrade with a 50% discount, go to our reminder - enter the data you gave when registering http://www.bolidesoft.com/a/user/
Here you can send yourself the current license with a secret code to update AMM with a 50% discount.
