AD Pro Licensing Problem

[Nigel]

I have recently paid £25 to renew my license to AD Pro. Following the renewal instructions, I should have received a new license activation key but nothing has been sent to me. I've checked my spam etc. The renewal instructions suggest contacting AD support if problems arise but none of the links in the program to support work. Has anyone had similar problems or know who I could contact about this? i can't find any contact details on the GAS website.

Thanks

Nigel,
Did you try e-mailing "ADLicensing@gatwickaviationsociety.org.uk"?

Thanks and yes I've tried emailing them but no reply so far.
