I had PComm 15 activated some months back via GOTD and remained legit. So ran 16 now using same email addy & pswd during installation. Worked right. Looks nicer than 15. Uninstalled 15 safely. I think it helps if you’ve had Ashampoo account already. If needed to get fresh one do it rightly and should be ok. Like I kept it simple with a Yahoo backup account and have never had any issues. Maybe trying with a really off brand, or a one-time disposable could cause issues.
Nice thing is so far Ashampoo free activations hold up compared to some (like Softorbit) that just deactivate. Rather just count on being one gen back as 17 is paid one now. Thanks SOS.
