First up I got the 0 and the O mixed up in the serial number so it rejected it with the customary "invalid serial number" but once I sorted that out the motherboard at lightning speed showed up registered bypassed any formalities, date of purchase info input etc. and just made the registered and purchase date today. I have the receipt and it is only a few weeks out, but thought I might mention it. Not sure if my error at the start caused it.
PS - I quite like the app and other than the above it seems to be functioning very well.
