Help! Error when trying to redeem download access code

Hi I got Cubase pro 10 about a month ago but decided to try the trial version and wait to redeem it to get the 10.5 but now i’m getting an error (Security Error #2FG0) when entering the code.

Can anybody help?

Nevermind, for some reason it would appear error, but finally was able to redeem the code and register Cubase
