The "user key" (utilization licence) for the non-limited version may be obtained by e-mails and only by this way (no postal sending). The price is 30 Euros (conditions for 2023).

There is no online help, no guarantee and the user key is not re-sent.

The accepted payments (only in Euros) are the following:
