I have been running MBAE for well over a year now until today when I did an update. Like others in this thread, I received the notification "Trial Period Expired" and that my license was found to be invalid. In my case, I was under the impression that I was purchasing a lifetime license for MBAE (version 1.05.1.1016) from an 'Authorised Reseller' via their Ebay store. In hindsight I understand that purchasing direct from the vendor would have avoided this problem (no need for any lectures), however I did not at all suspect I was purchasing an invalid license and the whole deal seemed legitimate. I was even reassured by the seller of 'after sales' support... I won't be taking advantage of any "great deals" like that again. I tried searching on Ebay for the seller, but they're account no longer exists. I checked for my PayPal transaction receipt, but unfortunately it looks like the transaction will not be covered under 'Buyers Protection'. I wonder how many others have been fooled by this seller.
