And where does one find the old number? The activation page is part of the old website, I can't find it on this new layout, nor can I find the number within the running Designspark software itself.
If following this process does not work for you please email us with your username and serial number at: designsparkpcb@rs-components.com and we will respond asap. This activation page and subsequent email has been updated within the past day so if you have any problems with it let us know and we will investigate
