The problem is not the purchase of the programs on your site (I understood very well that for each SMT you have to buy the new program separately for each one).
When I upgrade my smt32 to version 2.6.5.2 ZIP file and all the programs have disappeared (those that are original when purchasing the SMT32).
Now when I turn it on in the start presentation it's not SMT32 that appears but SMT24?.
The SMT32 cannot connect to your site code error 215.
