@Michaela-Y-Witte Are you sure you are using the correct code? You need a serial number starting with P3. Voucher codes are starting with G3 and only work in the online shop and not for activating a software.
The instructions state that they want my "voucher code". My voucher code (partial) is: Q0D6R-.....-WH4YP. I have have tried the second letter as O or 0, and with and without the hyphens (-). Today I tried my P3..... it didn't work either. What is next?
